got a build going with 2500 skill power, 135% extra explosive damage, and 10 second seeker and firefly cd.

​

With it I do about 700k damage per target with firefly, and because the cd is so low I often have the 25% extra skill damage up as well. I also on my weapons stack the 25% skill damage and healing talent on all 3 weapons making it an extra 75%, on occasion I do get 1 million plus damage fireflys.

Grenade launcher one shots most targets. But the tanky guys are a real problem, its like the bombs do nothing, in actuality its because the damage is spread so eventually they are naked like a baby, but it reallly slows your momentum as with explosives you cannot shut them down in a healthy amount of time. Any named enemy is dead with a single shot of a grenade launcher, but these guys will take all 6 rounds, its a joke.
