Contact Folders
I think what some people forget when it comes to guilds is that most games if not all others only let you join one guild….
Most games do, yeah. TESO allows 5 guilds as well I believe, but older games are certainly more restricted.
Most games also don’t bother with different folders for contacts, and at least some link your friends list to each character rather than the account. Useful if you only use specific characters with specific people, but confusing when you’re trying to add your friend’s 5 characters to each list. Then max out at maybe 50 or 60 contacts.
I’m not saying the OP is a bad idea, but our 5 guilds are separate contact lists already. It may not be optimal for some, but it’s a hell of a lot better than some games and there are bigger priorities for the developers.
