The subject line pretty much says it all. Not a very versed PvP player, hardly play arena at all, enjoy world PvP and the occational battleground (can't wait for cataclysm). On topic; has anyone of you more experienced arena junkies played around with a disc spec putting points in the shadow tree to get MF.
Seeing as one of the strengths of the disc healer in PvP is the damage output adding another nuke and at that one which may help you stay away from all that pesky melee playing ass-grab. Or is the trade-off too big and the added utility too weak?
