Ok… where to start?
Many thousands of players, limit 40 servers where hundreds of people can join? This is BS.
Seriously, if the server limit is 40, then only allow 40 people to even join the server and kick players who allow their bases to decay before they come back, opening up slots for new people to join. You have to have some way of tracking people. Players with no bases (at least a foundation) should not be saved in the server, and should not laying around unconscious.
Another issue on PvE
People are blocking off boss creatures and other people can’t get to them. We can beat down their doors and get to them either.
People are damming entrances to other areas, forcing people to go the long way around or even blocking off areas entirely. Something needs to be done about this.
