I was overgeared in NM, and things really couldn't even do much damage to me. I was just about to finish act 3 It was all but a formality that I was going to breeze through to hell. Then I continued to get teleported into a champion pack and like 50 other enemies. Spells on cooldowns, and no spirit. I had to sit there and watch that health fall knowing it was over.
Re-rolling a combo of a wizard and monk (since I have tons of intel gems now), and hoping one gets to 60. I first died at level 14 with a barb, then got to 31 with a wizard, my alt barb died at 40 yesturday, and now my 50 monk died. Let's hope I can continue to learn from mistakes and get to 60.
