I like the current difficulty level and don't think anything needs to be nerfed. Some fights / dungeons are easy / semi-easy and some are tougher which is nice.

Something I would like to change in the encounters to come is the amount of instant-death abilities. Yes, I know, we should learn to move and all that but come on... there must be other ways of making an encounter hard other than "if you get hit by this it's a wipe".
