I figure as I gear up more I'll peak around 150k hp with 3k health regen. The idea is that you can take quite a few hits in inferno still survive and kite to regen your life. I have 20k dps atm, but should go up quite a bit once I get more gear. The key obviously is getting the right combination of stats.
I'd rather play poorly and survive rather than have to play perfectly to kill stuff faster.
