frost mages survive so much longer though, and drink less from what ive seen.
been botting my frost mage from 45-58 over the last couple of weeks, and it hasnt died from mobs once (has been killed by horde a couple of times though :S). make sure you set it up to use cooldowns and things asap (icy veins/water elemental when they are available, mana gems when its about to die and has no mana etc).
keep the diary updated, makes for an interesting read![]()
