I'm just after some advice on spec and gear to improve my dps.
i sit on 3k-3.5k dps in heroics and push 4k if im lucky in raids.
i just wanted to know how i can get to 5k mark i see warriors doing these days.
my rotation is ww-bt-(slam when proc)-hs(rage dump)
Everything looks pretty solid. The only thing that stands out is you're massively overcapped for expertise. With 2/2 in weapon mastery you only need 18 expertise, or without it 26. Drop the points in WM and put them in imp. cleave or unbridled wrath and change your off-hand.. claymore, deaths bite, armageddon (or another betrayer :P) would all serve you better than the jawbone.
Keep Weapon Mastery because the other options are abysmal.
He won't have a choice come 3.1 (today if you're US, tomorow for europeans). WM is getting moved out of reach to the arms tree. But it doesn't really matter for the OP, he can comfortably stay expertise capped without the talent.
