Alright, quick question.

I'm ilvl 116 and I'm pulling 428 (Got to 440 once too, though I feel like I got lucky and when I die randomly cause I'm an idiot, I get to 390ish) DPS on average at the moment on T10. We've pushed him to 10% so far. I'm wondering, is my DPS any good? I'm struggling to keep my TP up at the moment.
