I gotta agree with the sentiment of the others here. If you wanna compete in tourneys and want to have a decent chance of winning then work for it. The ~2000h of CoH2 logged on my account are there for a reason. If you don't that's totally fine aswell, If I had spent that amount of time on my studies I would have probably been finished by now lol. You decide if it's worth your time.
T34/76, while being crappy tanks, don't get destroyed by 3 Shreck volleys. Shrecks themselves are fine, Volks with Shrecks however are not. Nerfing shrecks would just make Pgrens with shrecks awkward. Why do people want to nerf Shrecks if the core problems are Volks equipped with them?
