The only real abuse I saw was the vehicle crew population abuse. Other factors are more learn 2 play oriented. Also keep in mind that the balance team had a very limited scope with what they could actually play around with. Everyone knows USF crew pop abuse shouldn't be in the game but they weren't allowed to change that. They're hoping if this patch goes over well Relic will allow them to change more within the game.
and 2 mortar pits+bofors with self repair killing everything dynamic in this game with stupid 1 click murderyourmicro abilities is fine?
