Had already done it as Brewmaster before 5.4 hit, but with the changed to TeB for WW it made sense to actually try it out.
Killed it for the first time at around 550 ilevel (two weeks ago) but forgot to fraps it, as not expecting it to be this easy.
Important stuff to note :
Unglyph BoK, the heal effect is actually quite helpful
Use TeB defensively if risks of dying
Main issue is the boss criting you and having infest on you at the same time.
Use healing spheres if needed, the enrage won't be a problem in any case.
Hope some others can solo it as it's actually easier than in BrM in my opinion.
