Looks close to my stats, actually. I have slightly less DPS (like 17,500 or so), but more armor (like 5,500). My life per hit is at a bit more (950), and life per second with the healing mantra is like 550. 32k hp here. And yeah, regular mobs are fine, but a lot of rare mobs are rape. I think part of that is just this act has some lethal monsters even without being elite. You combine those abilities with being elite and you're pretty fucked.
Do you have any other damage mitigation going on? I personally have a string of ears, and I run with concussion on one of my skills, so that lowers damage coming in by quite a bit.
