My x4 DKs finally hit level 80 after 3 days and 10 hours played. I already had a level 80 priest, so I picked him up and started doing quests in Hyjal.

My setup is similar to Mosq2. I drive with my priest and my x4 DKs attack.

Well, a level 85 rogue appeared out of no where and one-shot my priest (instant angel form). My priest has shitty gear and only 20K health at level 80 so LOL. Not surprised.

Anyway, I proceeded to destroy the rogue with my x4 DKs. He didn't even have time to cloak or vanish. He simply died in 4 seconds. It was a great feeling.
