Lets talk about PaK 43 8,8 cm and KwK 43 8,8cm guns in this game

Lert:   If you can't pen things at tier 7 and 8 with 203mm pen, it's not the gun, it's you - and you average 378 dmg per match in the heavy tank with the largest hitpoint pool, most accurate gun and most pen at tier 7. VS tier 9 it becomes iffy yes, but even then 203mm pen with that accuracy is a lot better and more effective / useful than the russian 122 with 175mm pen and its 'accuracy'.   Learn to aim.
