I didn't roll the class for that spec (so far from an expert) but when using it in the world I noticed that it's very easy to run out of abilities to use other than a switch between tiger punch and blackout kick (to not lose the advantage of mastery) after I've used all other minor and major cooldowns. I probably miss something in the management of resources and it's not straightforward because if I google ww rotation I mainly get a priority that I mostly follow (alternatively the spec needs a revamp).
