mixed feelings...
1. no because a populated/full server is fantastic, there will be to many reserved slots in which the pubs will be kicked bc the members want to play, in results in angry pubbers thus lower populated servers
2. yes being, if theres a full server and theres no admins on at the time to warn/kick/ban pubs from breaking the rules, and disrupting the server, that will also result in population loss. although i think the private slots should be reserved for advisor and higher. (not saying it will happen, but it could also result in abusing this privilege)
