Less vector users. Job done there. Still lots of medics, but give it time they might try something else.
Way less aimpunch. It's easier to hose targets your already on instead of getting dinged by a flincher. Feels good overall. Will be interesting to see how that change progresses as everyone gets used to it.
Got a few free rank ups right away due to conversion of the xp system. Cool.
Barbed wire is crackup. Works well. Already seen people setup great ambushes with it on unique locations.
Bandage healing is interesting. I find targets before you would hit and they would duck away to bandage, now they duck away to bandage and then to heal, so it means the delayed engagement takes longer. Also far less assists from this too.
Snipers holding the sniper rifle (not DMR) seem to walk like a snail. Pulling pistol lets you go fast again. This is the only really annoying change I think
