In T11 we had several fights that were very BoH friendly. Not having been on the PTR I haven't been able to test the fights myself, but I imagine that a few of you have, so I was thinking about putting together a list of fights where BoH would be useful.
The two that come to my head right away are Alys and Rag. Alys you can put it on her when you aren't able to fly and are dpsing adds on the ground. I woul also imagine that putting it on Rag as he goes into the transition phases would work the same way it currently does on a fight like Magmaw, unless he clears all DoTs before heading under.
I imagine both of those are good uses for it, but I am also willing to bet that other have insight that I do not as to the specific mechanics of the fights so there are probably more.
