Now I'm only 57, but I am curious about this because the only way me and my wizard friend have been able to get where we're at is because we crawl through the dungeon with me going almost pure mitigation. I was at 1900 DPS a while ago, but didn't need quite so much so now I'm up to 3k. I think Belial's final phase with two people in party had about 3 million health, which means that if I could just punch him continuously it would take about 16 minutes to bring him down. So I definitely could see there being a faster way.
So I'm just here to research whether rolling a new toon would be a significant way to increase the speed of farming, or if 'monks suck' is just QQ.
