As with most guns in Destiny, when there's a very high attribute in one category, there will be a very low in other to compensate (high rate of fire/low impact - low rate of fire/high impact). I was thinking of what would be like to have a "Rocket Launcher" that spills a pulse with three rockets (same as Golgoroth's black balls, when you hold the gaze) with very low velocity, but excellent tracking that dodge walls, have a limited lifetime, with a decent blast area effect on explosion and that could be destroyed with some amount of shooting from the pursued, but that could be outrunned if you keep running from them. I imagine that for PVE, you could shoot a pulse of balls at a boss and change guns to continue DPS, and for PVP you could keep a Guardian busy trying to hit those balls, while you switch to primary shooting him down, or pushing them back from an area (run to avoid the balls, like in the Golgoroth's challenge). Would you have fun with one of those? Give it a like if yes!
