Im currently having a lot of problems sustaining a high dps when running raid with my guild. Thus i have been sat till i can figure out what is wrong. I am combat spec 15/51/5 The World of Warcraft Armory
Overall DD and DPS im running around 3200 but nowhere close to pulling 6-7k like the other rogues in the guild one is Mut and the other is Combat. My Rotation is 4Snd/5Rup/5SnD with using extra pts to evis every now and then. On trash I use FoN with the occasional blade fury and killing spree on mobs or 4+.
Poisons r being used Wound in MH and Deadly in OH.
Pretty well geared just waiting on a few upgrades in weap shoulder back but other than that all 25 man Tier pieces enchanted and gemmed.
Just lookin for some ideas to fix this so I can get back in on raid before Ulduar comes out
