I play a boomy and I feel you. My DPS is very inconsistent at times, overall it is usually between 45k-55k (ilvl 472). Been trying to play around with corruptions, had 2 TD rank 2's, but it is so hit and miss, some runs it is awesome, but most it barely procs, or when it does it is when most of the mobs in a group are dead so only hits 1 or 2. Ditched one of my TD corruptions and got 1 crit and infinite stars as they were on vendor, but I want a haste one and gushing wounds too, need to do some runs to see what difference it might make.
