The sweet spot for haste is 21%. With mythic Worldbreakers resolve u go up to 50% haste which makes your raging blow (with inner rage) exactly 3 seconds CD, Bloodthirst also 3 seconds, and bladestorm spin for exactly 4 seconds. Not to mention how fluid and feelsgoodman rotation is with so much haste. This is my talent build for ST: ... Tier 45 I guess you could go with Avatar also, depends on really how long fight last. Tier 75 warning! Carnage in pre-patch is currently trap talent. Maybe if u are heroic geared u can take it, but if u are 745 like me, don't go for it. With 50% haste and Endless Rage, u DONT need Carnage. Take Massacre and trust me on this one, it makes execute phase (don't matter how long it lasts) 100 times more fun. With thunderlord enchants, u can get back to back execute crits, and basically your rotation comes down to Execute -> Rampage -> Execute -> Rampage... 100% Uptime on Enrage much fun
