If you've been killed by a fusion grenade or used them, you'd know how unskillful they can be. You being outgunned by someone and you're going to die? Throw a fusion grenade! You'll either survive the encounter or you'll both be dead. It may not be as bad, but that's only because we've yet to see at its worst, once every sunsinger is using it, you'll see the nerf posts come. I've seen fusion grenades have the craziest hit detection in the game, sticking to someone who didnt feel close to the initial stick. I can admit that they CAN take skill, but most of the time it's throw and hope they stick and that's a free one shot kill.
