Well, I managed to get to Warlord Kalithresh on my mage. I have all epic 70 gear. I can't really get close to beating him. I had to spend over 160 gold switching talents around because different ones seem needed to get past certain bosses. I'm not sure how I'm supposed to be able to afford that every time I try to do the dungeon so, that's it for me for now. Maybe Ill see what the next update is like.
Is Hungarfen supposed to lock the mages frost nova skill? If so, that means I'll have to change my build just to get past him....which means Ill have to keep that build as long as I want to farm that dungeon. Not too fond of that to be honest. This is with epic wand, robe and book all at lvl 70...
