If we're not allowed to do that why make the server PvP at all?
It's still possible to enter PvP mode on a PvE server with a simple chat command, and anyone can do at any time if they wanted to.
This way you can only dmg people who also have PvP mode enabled/WANT to PvP on the server.
@ashen elk Very true. Still, people want to test out the new nesting changes or get their favorite/exclusive skins on the new dragon. Trolls are inevitable and it usually wouldn't hurt much if you're just insta growing Iconic E spawns to explore the map, but say you've been nesting for a few hours to try out the new upstatting or just got your favorite KS skin. Then a troll comes along and practically 1-shots you. Not very fun is it.
Sure, you could just sit in safe-zones the entire time or beg an admin for a restore but that also creates another problem. Admins need to be on constantly for no reason just to make sure people stay in line and remind everyone of the rules. ( I agree with @loud rapids )
I agree running 2 servers might be a bit too resource costly, even if it's just for a few days, so why not just make the test server PvE instead? Problem solved!
