Didn't it use to be either .com or .net for the individual servers? One would send you to survival and the other economy. But this was ages ago now. I'd support this because sometimes it's better being able to launch into the server you want, and not have to join then change servers
Technically economy and survival are the same server currently so I wonder if there would issues with the EULA if they split. Currently anyone can earn Leg keys on "The Server" by completing quests on Economy. If the server was split into 2 servers, then players on survival could only get them via purchases which might then be considered pay to win??
