Being able to move and cast Incinerate on my Warlock is the best. I'm annoyed that I'm going to lose it because I actually am just ADD and like to run around while I play. Usually I play melee so that I can run and jump around and not have it affect anything, but the movement-capable Lock allowed me to try out ranged. I'm leaning toward maybe playing a Hunter in WoD so that I can still have the movement.
