Blood Legion

Hey, I am in Arx Deorum on Windrunner, and we are currently progressing on H Ultraxion and I am looking for ways (in general as well for all bosses) to increase my burst damage at the beginning of a fight. Currently I hit between 46-52k dps (52 being a really good one) and I am not exactly sure if it is even possible for Surv hunter's to hit higher than that atm, I haven't personally seen it myself yet. I can sustain good dps, but my burst as Surv I feel is quite pathetic unless someone can tell me otherwise. But any help would definitely be greatly appreciated.
