There really is no reason to run daily random's unless you have bad gear and need those two emblems of frost you get. Just go do ICC 10. Shits a joke.

lvl 80 Paladin - Nirvash the Insane (fun achievement , look it up)
lvl 80 Shaman - Alekstrah
lvl 70 Hunter - Huntard
lvl 72 DK - Alekstra
lvl 70 Rogue - Alextra

Been on an extended break from raiding and wow in general for a few months though. My gear score is at 5500 atm.
