im a level 80 prot warrior starting to do heroic Naxx and the other 25s. My DPS rarely reaches over 1k. I get a lot of criticsm for that, but i do hold aggro. Ive respecced and worked my rotaion a little different. Id like to know what else i can do. My toon is Hatetank on zul jin server.
I'll probably get chastised for saying this, but here goes. Your hit and especially your expertise is quite low. Your HP's is high, which is good but I would think you may be able to lose some stamina by using some vivid forest emeralds and some guardian twilight opals. (+8 hit / +12 sta) & (8 exp / +12 sta) respectively to get you closer where you should be.
I'm afraid at your current hit / exp: if you start spamming HS; you're gonna run yourself dry with rage.
