Well, i'd suggest you use OwE and try mp3 for better results. It is advisable that you experiment with builds and find what is the best for your current gear. My monks for example do about ~100k dps each, some a bit lower, while other a bit higher (unbuffed). Dps depends the most on base weapon dmg/attack speed/and crit chance/power combo. Your crit chance is okay, but under 300 crit dmg is a bit low. Also i am using Echoing Fury on all my chars, and it gives a significant bonus to the attack speed. 500 all res is a bit low for mp3/4, tho. Better go around 650. It is perfectly natural for your char to die couple of times per couple of hours, but generally not above 15 times for say one session of 12 hours.
