To improve aoe during raid trash I have put blade dance on a seperate key in the same key sequence. The macro has trouble with cool down usage of the skill. I then switch out to standard macro for single target other than zul
Secondly my dps simmed on dummy unbuffed is 10.8k. The macro unchanged for single target is 9.9k pretty bloody good.
A whole K below sim? That’s too low. How fast are you running the macro? At 30ms I don’t miss any cooldowns.
