I’m planning on dipping a toe in ret-resto for arenas. I think there’s something to be said for this ret-reckoning build. Its more mana efficient than deep ret because it forgoes CS and relies on twisting, windfury, and reckoning procs to do it’s damage. Combined with pala and shaman utility, it could be pretty strong. I have a feeling any warlock will destroy it with tongues, though.
If it really ends up sucking, I have a warrior to play instead.
