In an automated guild I would not feel comfortable. Some things should be done by the one, who wants to lead a guild. Yes, thats sometime a lot of work, but you can assign officers and delegate. A real good guild climate is created with a personal touch.
Maybe, there will be a addon for automated playing in automated guilds
or just enjoy to play with your friends and not with bits and bytes .. or i'am only oldschool
(This should not be a flame, only food for thoughts)
