Too much expertise gemming and enchanting imo. If you replace 1 item with an item with expertise on it, you can switch out all those gems and enchants for something else. You normally find ~40+ expertise on current items. As well, you're super low on hit so look for another 1 or 2 items out there that you can get some hit with. Normally I'd find some item upgrades for you, but it's the weekend and I don't feel like it :POriginally Posted by Antdog
As well, there's a couple upgrades for your cloak. http://www.wowhead.com/?item=45319 is pretty easy to get, http://www.wowhead.com/?item=47275 is a bit harder but will help expertise instead of hit.
I'd replace KotJ with Imp Mangle, or take another 2 points out of Furor and get NSS and MSS for 4% more damage.
Aside from that, you have better gear than I do :P
