I've recently got back into Fusion Rifles and some of them are amazing. The FWC vendor's The Vortex has a base AA (Aim Assist) of 79 and with it's AA scope and Hidden hand perk, the fusion is able to get almost MAX AA. It's a sleeping monster in the crucible. Also, the Hitchhiker from dead orbit is a beast thanks to it's max impact. -In one charged burst, it delivers 7 bolts; each bolt delivers 51 damage. 51x7=357 damage per charged burst. If only 4/7 bolts hit your crucible target, they'll be OHK.
