Its not even about “potential” to work. It DOES work. Ive gotten over a 100 to join my guild recently in the past week by just sending out guild invites. True not all of them will be quality guildies but some of them definitely will and already Ive found very helpful folks from doing this. New players, people who just switched realms. People coming back to the game who find themselves in a dead guild. There are plenty of good folks who arent in a guild and who appreciate the invite. I get “thank you for the invite” SO much.
