honestly, it was fine, i only had a slight issue with Fire Damage, 800 Fire resist and that #$#% would still do mad dmg, arcane also ... sorta, I just think fire damage or fire resists are bugged somehow, with like 400 resist to poisons I can stand in poisons all day.
but with like 1000 resist to fire you still get pretty beat up... (feels no different than having like 0 fire resist).
I have also noticed this, and even as a Monk, who's primary cool-class stat (Dex for Dodging !@#$) gets negated ENTIRELY when standing in a pool of poop.
I can stand in plagued pools no problem. I just tank right through that %^-*. I have nearly 900 resist to everything. And because I have over 1200 life on hit, plague does just about nothing to me, EVEN THOUGH I CAN'T DODGE IT AT ALL *grumble*.
But if a Desecrator or Molten thing ends up under my feet, forget it, I have to Tempest Rush my !@# out of there. I can handle one tick of Arcane Sentry before I'm smashing my oh-$%^- buttons. But whenever it comes to any fire attack, I take an inordinate amount of damage that far surpasses that of any other magic type.
Really, the damage wasn't the problem. I went from MP4 down to MP3 not because I couldn't survive MP4, but because MP4 was just incredibly slow since the mobs have a *!@# ton of HP. I can't imagine trying to kill mobs on MP5+, not because of ridiculous damage output, but because of the insane amount of HP they have.
