A titan or warlock doesn't have to worry about timing, they walk into an area, and if they get into trouble, bam, they have a nuke, and sure, its a one shot, but if aimed right it can kill everyone in the area, gunslinger, you have 3 shots, maybe four if you have the one exotic, so you are limited to that, with a warlock or titan its possible to get 6 kills, with a hunter, you can get three if have good aim, maybe more if you overpenetrate or have the exotic, and you have to activate before you get into trouble. Blade dancer, you lose all ability to shoot, so you have to dash in to others, with shotguns and crap, I've watched plenty of people activate it get one kill and die. As for sunsinger, well thats really a pve super, though it has uses in pvp, and allows to spam grenades and melee for a few seconds, or revive randomly, which is awesome in strikes. And ward of dawn, I've walked into one of those and shot a rocket into a titan's face, and the titan survived, it offers undeniable zone control, which is incredible in control. Now what is op in PVP is auto rifles, scout rifles and handcannons don't really stand much of a chance, they are far to accurate and can decently engage enemy's even out to long distance, at medium to short distance they are hands down the best primary weapon.
