I have done a few BGs in the last week and one thing I love is the lowered cd on chain lightning. I am guessing that CL might be hitting for less, but now being able to always cast LB-CL combo is amazing.

But anyway, I was wondering if anyone running 4 or 5 Shaman went for full mastery? I would say running solo, mastery would help out a bunch. But I cant really figure out if mastery would help out my team. I would guess it would, but to the loss of a little crit worth it?
