1. Please reduce the amount of cleaving monsters having them absolutely everywhere encourages other players to kite them to low leveled players when they're bored. I know that's against the rules but it is so common right now please gives the GMs a break.
2. Add non-combat objectives and goals to the instance. Please, this would make it so much more interesting if there was sightseeing, gathering, treasure hunts, or other little side deals that weren't purely focused on killing stuff that would encourage players to enjoy this beautiful map.
