Guesting into full servers
i doubt it since the server is full.
Maybe, maybe not, we’ll see once the January update comes
Give a man fire, he will be warm, set a man on fire, he will be warm forever! …or dead…
Yes, you can guest to servers that are marked as full. Obviously, you will stand a greater chance of being put into overflow for some zones compared to non-full servers, but you can still guest there.
