Perhaps input on shot prioritisation could be put on, could that be a factor in dps loss?
We could really do with a hunter sticky thread - i'll investigate and try and get something on here - verified by our resident hunter experts! (looks to Iluria, Beli and Chewwie!)
Doomcluck may be able to assist you with crafting an epic chest if you can help supply mats. Give me a holler if you need anything transmuted.
