Problem with boss respawns is this: Trinity classes need to kill these bosses to do their mainline quests, but the long respawn times makes that damn near impossible. Klll Baron .... wait, kill mirebreath .... wait, kill darkness sprite .... wait even longer.... It is fkin annoying. Why the HELL are these wankers tying so many boss kills into main quest lines? Either shorten the respawn times to an hour or so, or just remove the damn requirement.
