Running it, yeah.
I made general improvements since last 4+ min time - the addition of Dominate and whatnot, but here's the real caveat: I cheated a little and respec'd into Ignite, knowing it would never be as good anywhere else but here. Knowing I would feel dumb about picking it up just to kill pylons, I picked up Web Grenade too and used it to mule a purple set. At which point it's not horrible in general play anymore. As long as you use it to kill off bosses instead of making whole mobs scatter.
My attacks here are basically just Sniper Rifle, Dominate, Ignite, and Full Auto. Can't be chained, but I always have a Caltrops/Acid Mortar/Poison Trap/Triage Beacon up to fill in the gaps. LOTS of procs all over the place (5 in Caltrops, 3 in Acid Mortar, 4 in Poison Trap, 4 in Dominate, 4 in Full Auto...).
All this with soft capped defense, capped s/l res, mez protection, and good regen is a fairly good deal 🙂
Note I don't know anything about how Ignite procs, if at all, so I put ATO's in it. But I wonder if it does crazy things like Burn does..
