My current spec is a mish-mash of Holy/Disc talents. Most of them are for healing and mana efficiency, but I still have some for when I was grinding, i.e., the increased holy smite damage and wand damage. I was going to respec out of those talents, but the expansion is so close, so I thought I would wait the extra month and a half so I don't have to respec again to start the grind to 70.
How much are respecs? If I can afford it, I'll respec to whatever you think would work best for raids.
