I like the voidknight but the soundeffect of the devouring orb skill drives me insane. Especially when the skill is on autocast. It would be better if the first part of the sound is left out (when the orb is cast) and only the shooting / explosion part remains ingame.
Try it yourself, devouring orb + autocast and listen to that non stop for 1 hour. Let me know what you think!
