Coordinated for what exactly? I could slightly agree if true north didn't exist, but what coordination is required outside of the tank always holding the boss north, which isn't difficult given bosses tend to be pretty static as its generally mechanics that force players to move around. Hell, even when bosses do move, they reset themselves after the mechanic fires off and warp back to the middle lol.

I just don't really see the benefit of them. They're not difficult to maintain and they don't really add anything imo. If they stay, they stay, if they don't then they don't and nothing really changes if they go.
