Ty.

My own personal opinion:
Holy is my personal choice, healer for dungeons (or tanking/dps if you got the gear) AoE is op
Prot if you first get 11 into holy for the aoe. Tanking is fun!
Ret is nice and op until about 40. If you just plan to solo and quest, ret is the way to go!
In all honesty spec doesn't matter when your leveling, play around and enjoy the journey
