I think that a server paywall would split the community and would likely be empty [small] cough cough [/small] , an example is gold servers, most people with over 500 or so hours has gold, yet they still choose to play non-gold servers and thus no hosters are hosting gold servers. If people are split (say 1 friend has the pass 1 doesn’t they can’t play with each other on a preferred official server) the servers would likely be emptier and the 2 players would migrate to a community server, defeating the purpose of official servers, and this scales largely with a group.

Why is there no “I do not support a server pass for official servers” sort of option on the “Official Server Pass” section poll? Someone is bound to disagree.
