And they better T-34-76 in role pure AI/AT. Much better.
Too late. In coh2 T-34 is early tank, and you can not increase its firepower or survivability. No smoke, additional mg, hulldown or armored skrits. Build T-34-76 in late game like building M3A1 in late game.
Compared with T-70, the KV-8 gun is pathetic.
1/2- One is an assault gun which has equal AT capabilities as the proposed KV8 with a lower health pool and the other is a "pure" AT vehicle which gets it's AI from crushing (which excels). A tank that has 160dmg, 640hp and medium rof will always prove useful to complement a push (or just amass a huge number). There are moments i'll rather have 2 T76s than one 85s (specially against super heavies).
M3: on the same way, if the map and opponents allows it, i'll get a 222 to hunt a Katyusha, i would do the same if i have Guards against a PW.
3- T70 doesn't have a flamethrower and 800hp. Vet1 is a light bonus when talking about performance boost. I'll rather have to buff something slightly than nerf it (see croc).
