I don't do PVP much, just started doing it a few weeks ago to finally hit rank 3 crucible on at least one character and now for IB. It's fun, even if some things are over powered than others, gives you a challenge... I don't really have a problem with fusion rifles, but special ammo in general shouldn't be as common as it is. It should drop like heavy ammo and 1.5 more often than heavy and you start with 1 magazine. I do however think that fusion rifles should not be able to ADS or the "spread" on them should be far less predictable/controllable. Right now they just climb the ladder, while I feel like they should zigzag around and move in arcs, not just up and down. Definitely don't have a problem with shotguns, bungie just needs to put in some none close quarters maps so that rumble isn't just a shotgun fest. Changing how often special ammo appears would solve the problem to though. Sniper rifles should have a penalty to accuracy after moving or force you out of ADS if you move (not referring to looking around while in ADS, just to "dancing" while in ADS), but i've begun to not care and have started to be able to out snipe the snipers with my hand cannon with some good foot work and less predictable movement. Also being conscious of how you are moving helps too. Be less predictable with your movements and you wont get pwned by them nearly as often.
