It works. One problem I've noticed is that a missed mutilate can mess things up. I think I may have missed 2 in a row during the second sequence so had no combo points up and was stuck on eviscerate. It reset after the initial macro for slice and dice re-queued. My rogue's dps is awful (she's in all PvP gear too) but I saw about a 400 to 500 DPS increase from 1400 to about 1900.
