Victory Rush

Useful both when soloing and when doing a 5 man instance. You have to land the killing blow to get Victory Rush, but that’s no issue when soloing. In a group, execute will get you the killing blow pretty often as well. (Note that the rage cost for this ability itself is zero) The short duration does limit its use somewhat, as you can’t always have a fresh mob ready to kill in that time.
Commanding Shout

A nice new shout. It has a major downside though; it doesn’t stack with Battle Shout. Warriors are understandable unhappy about that.
Spell Reflection

Core usage of this ability lies in PvP, but it has its PvE moments too. Being able to see exactly what the enemy is casting, you can pop Spell Reflection at the right moment and, depending on whatever was being cast, cause some serious problems for the target. It’s a little high in rage cost, and the inability to use it in Berserker stance is too bad, but reflecting polymorph is good stuff.
Intervene

This skill can have some possible uses, although it’s mostly just intercept with a new name. The “intercepting” of the next melee or ranged attack could have merit in certain situations though.
