all pvp, it's terrible, I just forgot how bad it was.
IB right now for me is everyone hanging back with sniper rifles especially the ice breaker because of ammo regen, and just popping shots, or if someone is running around they most likely have an AR in their hand.
Ice Breaker is terrible in pvp. Too slow to fire. Those snipers should be easy to deal with. Grab a faster sniper or use cover and sneak up on them.
ARs, Handcannons, Scout Rifles are all super viable. There are a few decent Pulse Rifles too. You're deifnitely not restricted to ARs in your primary slot to be competitive.
