Neltharus and VP feel really tight, and the trash hurts. VP you better bring two magic dispells or people are going to die. These keys are going to destroy pugs, holy cow.
Please bring these in line with the other keys.
Also, for the love of god, please fix re-spawns. You should respawn either at the last boss you killed or the start of the dungeon, whichever is closest to your death location.
Dying near the end of Halls is a ~3:30 runback - unacceptable.
