KNIVES: Didn't realize you were out, next time I have to try to make my way around and introduce myself.
As for the BA role if you aren't running heavy ammo and DOT 44 its pointless
I try my best to listen to all hits on my equipment (PC with Hydro) but sometimes it's impossible without a heavy twack to it IE: why aegs are better cause you can shoot a quick burst in semi auto tap them with a few.
As for the campers not sure who you were referring to all games eventually turn defensive unless the objective is constantly moving. I thought the first game of VIP hill attack was pretty much text book for suppressive fire movement.
