Suppression effect got an unnecessary buff - you pretty much can't fight back if you're suppressed (that means whoever shoots first, even if they miss they pretty much won that gunfight).
Tanks feel paper thin against other tanks. DICE nerfing the foregrip was completely unnecessary and it's pretty much utterly useless - they're trying to force people using either:
1) No under barrel attachments (if you're Assault, you can opt to an underbarrel launcher but that'll remove medpacks)
2) Bipods (more campy gameplay).
I welcome every other gameplay fix such as MAV riding and weapon buffs/nerfs though. But the negatives of this patch pretty much makes it nearly unplayable for me.
