Wanted to know which class I should do because i decicded to make a caster and rounded it off to these to. Which would you guys go with and why? Also had a healing related question. If i made a priest for healing what should I do disc or holy and why? Thanks for helping me out in advance

I say mage. I have a lvl 85 mage. Not a big fan of shadow priest. But i do enjoy doing holy heals on my priest though. Theres aoes also hots. I have heard that disc healing is also fun. so if you want a dps i say fo for mage but if you want a good heals go with priest.
