Post-0.8.6 changes in efficiency rating

Hello everyone,

I really, REALLY didn’t want to get into this topic and postponed this article several times already, but I guess the time has come. I didn’t want to do it mostly because I dislike the XVM mod and numbers, but whatever.

Anyway, here’s the background: as some of you know, the wot-news.com server (that currently hosts FTR) was made by a Russian player Edrard. Edrard is – amongst other things – the creator of the classical Efficiency Rating system (that XVM uses). Some of you might have noticed that post 8.6, your efficiency rating changed. This is due to the changes made in the formula. Edrard explains:

And so it was that with the release of patch 8.6, the artillery, which earlier was ranged from tier 2 to 8 became tier 2 to 10 – and everything would be fine, if the tier 8 artillery suddenly didn’t become tier 10 and not only its tier was changed, but also your account’s old statistics, in which, vehicles tier 8 became vehicles of tier 10. As a result of this, many players had their average tank tier increased. For example, mine (previously 7,65) became 7,77 and I lost 3 points of Efficiency Rating as a result. However, some player’s ER dropped by as much as 10 points.
In the beginning, we planned to simply introduce a compensation by re-calculating (compensating) the artillery tiers, so that during the calculation of average artillery tier, tier 10 arties would count as tier 8, while tier 2 arties would stay tier 2. This would certainly do the job and would produce the desired effect, but in the future, it could bring a number of problems, such as:

- real average tier would differ from average ER
- in the future API from Wargaming, average tier will be calculated and it wouldn’t fit the ER calculation
- third-party (side-) developers will have to take the fact into account, which can lead to errors and misunderstandings

In the end, after consulting the colleagues and guys from XVM, we decided to implement another solution. We won’t implement the compensation at all, but will re-calculate the rating boundaries. At this moment, they look like this:

After the re-calculation, they will change and most likely decrease.

Silentstalker: This was posted roughly two weeks ago. Talked to Edrard today and he actually stated the re-calculations are ready and have been passed to the XVM guys. You can thus expect the new system soon (I am sure it will be announced)

T-34-3 – new premium T8 preview

Meet the replacement of the famous Type 59

T-34-3 – Tier 8 Chinese premium medium tank

Ingame description:

The T-34-3 medium tank was to be a modification of the T-34-2. Unlike the Type 59, the T-34-3 featured reduced armor. The design was developed in 1957. However, mass production of the Type 59 was started in 1958, and the T-34-3 project was discontinued.

T-50/MT-25 changes

As you probably already know, the T-50-2 is getting replaced by MT-25 and moved to tier 6. This is how the transition looks in the 8.7 tree

First, let’s have a look at the 8.7 tier 4 light tank T-50

This is how it looks in 8.7 (elite, modules)

shot_030

shot_029

At first glance, compared to the 8.6 T-50, following was changed (in elite configuration):

- speed limit nerfed from 60km/h to 52 km/h
- weight increased from 12,68 to 13,95
- turret traverse speed buffed from 45 to 48

Until it gets entered to gamemodels3d system, we won’t know more.

The MT-25 is a new tier 6 light tank, unlockable from KV-1S, that continues the line to KV-13. Here (modules, stock, elite):

shot_035

Compared to T-50-2 in top configuration, MT-25 has following changes:

- it uses the same top gun (57mm ZiS-4)
- +10 hitpoints (570)
- +50 engine hp (600hp)
- 25,72 ton (massive nerf, T-50-2 has 14,69)
- minor ROF buff (22,22 compared to earlier 20,69)
- traverse speed buff (48 from old 38)
- turret traverse buff (48, earlier 45)
- armor buff:
45/40/40 hull (earlier 37/37/37)
45/45/45 turret (earlier 45/40/40)
- same radio and viewrange

4.7.2013

First, to all American readers: Happy Independence Day!

Anyway, before the 8.7 gets downloaded on my comp (if I manage to log in, I’ll post pictures/stats of all the new vehicles), a quick Q&A session:

- in 8.7, the gun accuracy will be the same as in 8.6
- 112 was removed from patch 8.7, because it needs further balancing
- since 0.8.6, the Fjords map winrate of both bases was 50 percent (no disbalance)
- there were rumors that the new Soviet branch will bring a Maus-style Soviet heavy tank (SS: no idea where the Russians got this from), those rumors are false
- the three most important factors for WoT’s rating system are winrate, average XP per battle and average kills per battle
- the IS-6 ingame has mechanical transmission. A player stated that the mechtrans IS-6 had historical maximum speed of 43km/h instead of current 35 km/h, SerB will investigate
- 8.8 patch tier 10 Object 430 will not have the 122mm gun (Object 430U)
- other premium vehicles in the past were not possible to sell for gold, because they were never changed seriously enough
- when counting cover, two fallen trees count as one (their camo bonuses don’t stack), but two bushes in one line do stack – however, one bush and one fallen tree don’t stack
- the VK100.01 is a real project, based on one German book, allegedly, Yuri Pasholok was one of the first people to get that book in the former USSR
- regarding the Panther changes: “Expect a small buff to tiers 7,8 and 9 of that branch”
- WoT won’t have for example completely destructible all objects, there would be a problem with server synchronisation and load
- in order to pay for itself (without no profit), WoT has to have at least 50 thousand players around the world
- during the hull unification, T-34 and T-34/85 apparently won’t be unified, T-34/85 and Type 58 will both stay on tier 6
- the reason various trees of various nations don’t have the same tech order (for example one tree has arty branch on the top, while another on the bottom) is to make transitions between branches better visible
- both 112 and 113 have 68 degrees frontal armor slope
- apparently, WoT Generals account will also be unified with WoT

Pretty cool video…

Good mooooorning, Vietnam!

Today, I have a really cool video by player Arti25 (RU) to show you (Thanks to Dom1n, EU), with Object 261, T92 and Batchat arty and it’s…. well, just watch it :) I liked it a lot.

 

3.7.2013

Just a reminder, guys, the 8.7 test apparently starts tomorrow. On one hand I am surprised that almost nothing has been leaked about it, on the other hand, the source of this info is very reliable.

- links from and to the British arty branch? “Wait for open test”
- IF the E-50 tanks are unified (definitely not sure), E50M will simply become a hull option for the E50
- a “Wittman-like” medal (for a big number of kills) won’t be implemented specially for lower tiers, because the developers don’t want to encourage experienced players to go hunt newbies, tier 5 (Walters-Radley medal) is already not sealclubbing/pedobearing
- the rule that “weak gun = limited MM” applies only for premium tanks
- if Sturmpanzer Bär was introduced into the game (SS: SerB emphasized the “IF“), it would most likely be a part of Sturmtiger’s branch

SS: Sturmpanzer Bär was a superheavy (120t) 1943 self-propelled mortar project,armed with a 305mm mortar. The project was basically rendered obsolete by the Sturmtiger project and cancelled. This is how it would have looked:

p1

- with the introduction of researchable hulls, GW Tiger P won’t become an optional hull for GW Tiger, because otherwise there would be a hole in the respective tier
- lowtier tanks, previously leaked from supertest (such as AMR P103, LTP etc.) won’t be introduced at once, but at different times for each
- new British and Chinese tanks? “will tell when the time is right”
- SerB doesn’t know yet what the Japanese tanks’ base color will be
- JagdChieftain (CTR) in WoT? “No comment”

Jagdchieftain:

cb3ad719cc57

- SerB won’t disclose the exact mechanism, how XP points are gained from combat, he only states that the XP gain is judged by active participation in the line-of-sight tank battle (as in, tanks have to see each other)
- no plans to give additional XP/credits for protecting allied tanks with your tank’s hull
- it’s too early to tell, what impact the 8.6 had on medium tanks
- SerB states that while the statistics are yet to show, arties are unlikely to be directly buffed. Instead, devs have ideas about some new artillery gameplay elements, which would raise the arty effectivity, but the concept is not finalized yet.
- SerB states that while he doesn’t remember whether the IS-6 in the game has electrical or mechanical transmission, you can check it yourself, if the vehicle can turn on the spot, it’s electrical, if not, mechanical
- the German 50mm L/60 gun module is too light in the game, it should be heavier, but this has low priority
- terrain passability is counted according to the point, located in center of the hull (SS: if the center is located on the road, while one track is located on rough terrain, the game will use the passability of the road)
- Russian players started massive whining about the T-44 being underpowered after 0.8.6, it was dismissed as… well, whining.
- StuG IV in WoT? “No comment”
- SerB believes he does have the T92 light tank documents/drawings, because The_Chieftain (US forums history expert/developer) sent him a lot of stuff
- SerB considers the “miniquest” (combat task) principle okay, but its implementation was a bit off.
