I am sure there is some logic behind it to prevent 'jerk' behavior but it really is a bad design. I have had guilds split in past games where leaders / followers disagree on direction for new content and a new guild is formed. Having to wait an arbitrary 24 hrs just seems silly to me. I had friends who recently left a large FC to start their own smaller FC of close knit real life friends and had to wait to do so, it was bad enough they were sending texts and emails to coordinate people being online to sign the charter but when they went to they were denied.
