Jrox, running through deadmines with my 70 warrior was super fast. Using Whirlwind and cleave and retaliation on huge packs of mobs, I cleared it quickly.

I'm going to do a run tomorrow with the 70 warrior + 4 new guys, and a run with 30 paladin + 4 new guys, and see which one has the better XP/hr.

I'll post my results.
