The blackzone cities (Arthur's, Merlyn's, and Morgana's Rest) should be removed. Players can create public hideouts for other players to use and should be encouraged to do so. Let the sandbox thrive!
The blackzone cities don't have any crafting stations. There is already a lot of room for players to create their own player run cities using hideouts.
The blackzone cities are necessary for solo and small group players that can't maintain their own hideout.
Agreed with Lany. There are is decent chunk of the player base that does not want to be in the zerg life style. These cities are a perfect place for them to reside.
