irl wait a minute this isn't real life those damn amazing graphics get the better of me from time to time .
I think your missing one very important tool in company of heores its called flanking/ambushing. the t34s aren't meant to go one on one with a p4 your suppose to use a whole host of units to take it down. heck coh in general isn't meant to just have 1 on 1 engagements your suppose to use all the tools at your disposal. that means infantry, at guns, tanks, mines, etc... (or what we all like to call Combined Arms.)
might be nice to see an upgun t34 kinda like the sherman. (maybe give it a 57mm gun (that gun was better actually for AT.) or drop the 85's doc and make it part of the faction. as right now t34 feels like the t70 does a better job at its role and right now its role seems mostly for ramming. but straight out buffing it to be just as good as its counter part isn't the answer i feel. right now the Russians as a faction are better than the Germans in 1v1s imagine if they could simply go toe to toe with the Germans p4s. O_o
Wifi, we are talking about a very expensive unit here. This is not some cheap tank that is used for flanking ect, if you buy a t3 building and make t34s you basically commit to not having any AT at all other then those useless anti tank guns. You wont be able to afford a t3 with t34s and t4 with su85s, which is the the only real counter to german armor. The t34 is just not worth that, its a waste of money. The t70 does better anti infantry and the t34 is a joke verse any type of armor. Its only purpose is that ram ability, which is a waste of resources big time. Most pro soviets are totally skipping t3 and just builiding su85s because its pointless otherwise. Soon as the p4 rolls onto the field its game over
