As someone who plays mostly german and 2v2 games, this is my problem with the SU85:
I know my opponent will go SU85, sooner or later. Whatever tank I'l make will have to Stay Behind my infantry if I ever plan to attack where the opponent is prepared, so naturally that means more Infantry and less tanks, as well as PAKs (since the patch).
PAKs work fine (still a bullet spunge), but it's a bit odd that I have to use them as an Offensive unit, using my tanks to protect them from infantry (staying behind them) instead of attacking with my tanks and using my PAKs to shoot enemy tanks. I find my tanks, for the most part being the reserv, because there is usually no way for them to approach without being harassed from afar by SU85s.
I've found myself using cheaper Fuel units (scout cars, halftrack), more and more. Still lacking a mobile anti tank gun though (I loved the stug before it was changed).
I wish the soviets had other options than just the SU85 (still has too long range and speed for my liking), or that the germans had some cheaper more spammable vehicle to throw against it.
