I wouldnt call this generally alright, he seemingly did not quite understand the core of the build he's playing.
@quasi matrix you're playing colossus warrior, your defensive play comes from absolutely stupid revenge spam while refreshing ignore pain. The reason this works, is because we run a talent that lets 10% of our damage add to our ignore pain damage prevention. When pulling packs, you'll end up having damn near infinite rage, especially in the beginning. What you're doing, though, is pressing thunderclap and shield slam is if you were still playing Mountain Thane.
Generally, you're not messing up a lot but your dps could probably be doubled while still retaining similar defensives.
TLDR: click revenge more in aoe fights while ignore pain is up
