Hybrid spec that goes at least 37 points in Arms for Unrelenting Assault (reduces Revenge cd to 1 second and increases damage by 20%) and then goes down the Prot tree for Improved Revenge (increases damage by 60% and it strikes a 2nd target). Basically a prot spec that pumps up Revenge as much as possible for insane damage. Last patch of Wrath actually nerfed it because it was TOO good in raiding, but its still really good, especially in solo content.
