It seems weird that guilds try so hard to get the perfect balance, then a few chars don't log on on a night and they can't raid for it. They all seem really defensive about membership too. Like preventing your alts from joining other guilds.
It really is just a glorified chat channel with the exception of the guild bank and teleporter. I'm waiting for the day when someone just starts up a guild that is a chat channel. Want to join, hop on in. If you're an ***, the moderator will ban you. Suddenly, there's never a shortage of players, and you can raid every night if you want to.
