If Warrior's DPS just boiled down to pressing fell cleave six times and tossing in an upheaval, we'd be seeing absurd margins in the top percentile of parses compared to the other two, as opposed to the very minute differences we're seeing. While the rotation is certainly daunting at first, it's not really the hard part about WAR; the largest issue I've encountered is timing and opportunity. Not only do you need to time your abilities to line up with inner release, but inner release itself has to be timed with the fight and the party in order to have as great a window as possible to fit in your burst rotation and maximize its damage.

Heck, I don't even think this is a bad thing, I LIKE having a tank that is challenging to play, but overcoming that barrier should see far greater rewards than what we're seeing.
