And then there’s the point of there not being a coherent line. Have you looked at the American auto-loader line!?

You have the M2/M3/M5 light tank line, the M7 was designed as replacement for the M5, but is a medium tank in a line that is nothing but light tanks up until tier 8.
After that you get a tank that is completely unrelated to any other tank in the line and which, frankly, should be on the other side of the tech tree (before the T20 most reasonably).
Both previous tanks were cancelled before they were put into production, and were succeded by the M24 Chaffee, which is in the other light tank branch.
After the T21 (which should be just as much a medium as the M7) you get the T71, an autoloader tank designed to be airmobile (which was also a requirement for the M41, but it got too heavy). Not to mention that the T71 is a mix between 2 projects, as per WG fashion.
After the T71 there would be 2 more viable light tanks (T92 and (X)M551), but WG decided to suddenly make this an auto-loader branch.
The T69 has nothing at all to do with the T71 other than that it happens to have an auto-loader.
The T54E1 was a heavy gun tank (105 mm gun), the only existant T54E1 in the world has a sign next to it saying “Heavy Tank”, yet WG decides it’s a medium tank somehow.

Please, don’t talk about coherency.

Like, really?
I’m paying to play against humans and the only thing that counts is my belief that i still play against humans only. If it’s gone, i’m gone too.
I don’t care if i’m better or worse than computer – why should i? If i want to play against machine i have plenty of singleplayer games…

why don’t they just introduce them as perks and skills for the crew.
