in his post, Storm shows how the T-54 turret armor will change. Every model, that gets transferred to HD quality, will have its armor changed – some slightly, some significantly so. Most of the time it’s about the increase of number of armor zones. In connection with this, Storm admits that they made a mistake, when they made the 9.0 turret armor for the test. Check this out. This is how it looks now (8.11):
This is what it was changed into in HB Test (or the current running test round)
And this will be the final 9.0 release version:
(the scale between pictures is slightly off, so no, size doesn’t change)
This is also the way the Chinese will be reworked, when transferred into HD, but Storm states that it is not decided yet, what (if anything) will be done with Type 59 armor. I asked around and the info is however that it is unlikely its armor will be touched due to player reactions.
