I have a holy pally with t5 gear to t6 gear. I have mixture of ret and prot gear in t4-t5 gear.
What is the best for leveling in WotLK right now. Im sure some skills can change. and Im thinking of changing to RET for the great DPS that they are showing to have.
I do believe that you answered your own question. Yes, RET is currently the dominant leveling spec. However, I suppose it may differ if you are one that may want to be healingor tanking 5/10mans along the way.
