Not going to repost all the new stuff, you can view it here.
They're moving tactical mastery from Arms to Protection, which seems to help protection tanks, but may partially gimp the dps warriors.
Rampage looks pretty solid: +200AP every 3mns seems pretty efficient. Endless rage at a first glance seems like it could combo very well with execute spam. Blood Frenzy + Endless Rage + Recklessness + Execute spam = a lot of damage (and aggro).
I'm a little disappointed Vitality is a tier 8 ability, but an added 10% stamina from talents, on paper, looks to be amazing. Devastate also looks to be very effective. I enjoy the fact that Last Stand now no longer requires you to dump points in Improved Bloodrage as well.
So, does Rampage outdo Endless Rage? the fact that it's a 3mn cooldown and lasts for 30 seconds looks like could provide a lot more sustained dps than a 5mn cooldown 10second burst dps.
