I'll be honest, I don't even bother yet. When I get the greater blessings, I will be buffing the locks (and the 1 imp) with wisdom and their pets (except the imp) with might.

But as I'm only level 46 (yay 4 levels this weekend with raids and solo on the other toons) I don't bother. Life tap + drain life beats the snot out of wisdom. And, lets be honest here, for me at my current level and progress in a almost purely questing area, I can kill things faster then the little 20 or 25 mp5 will come into play for sustainment battles.

If you're higher level, try a few and see what works best for you. I honestly do not like the new BoS, I miss the extra damage from the blocks.
