since when are tanks in the game "a problem?"
Use the truesight system in coh2 to bait enemy tanks onto your mines, det charges, ambushes, faust/atnade squads and they will be sitting ducks.
Tanks need infantry to support them, including checking blind spots on city maps.
Relic is not going to rebalance the game because your general impression of the east front is that everything was a nice big open corn field. For every Kursk there was a stalingrad/berlin/vladiovostok
Your post leaves me in doubt if you are serious or just trying to defend something about the german side.
But assuming you actually mean what you ask: tanks are not a problem as such. Only on the city maps.
Tanks should be at a disadvantage in cities, but they are not in this game. And the point is, that the deterrent that infantry was against tanks in cities, is not present in COH2. Well, at least not on the soviet side. You can't deny that.
