Just hit 48 warrior, priest 3 mages, I've been fury with my warrior which has been good but when I hit ZF mobs hit like trucks but I continue to go that route.

Today I saw a streamer called SlothxHero, doing the same combo he was doing warrior prot gathering more mobs, surviving longer. His mages we frost and a bit of arcane.

I respecced to prot which is so much better, thou Ive kept my fire mages the same spec I just hit 48 which I get the new rank for flamestrike. Ill see how that is otherwise Ill respec to frost. For me I dont care for the bosses at the moment I care for the grind.
