Personaly, I want to see more different AI patterns and more control over battle field, by that I mean, larger Add groups, probably in anology to mmo's heroic versions of the dungeons. Also more positioning like AoE's and run around for AI (ex: warriors need to have speed in orger to turn boss away from DD's and Heals or Run for your life encounters when group member become Mind controlled and buffed, assisting boss and taunting others to attack him).
