It´s pretty pointless to talk about the setup of tanks rigth now. We don´t know whether we will get a proper tank system in the next patch. If it turns out to be the retarded crap we have atm, where Shermans are nearly the equivalent of a Panther, Germans need a similar number of tanks as the Russians - and that´s bullshit.
Just fix the tanking to resemble anything even slightly plausible. Give German tanks the advantage in firepower and give Soviets more tanks. If the German 75mms struggle versus T-34s also - I´m out of this mod.
Also keep in mind that the only server that´s online atm. is the 128 player server (with about 100 players online every evening). If possible the layout should consider that amount of players, when adding tanks.
