Hard to maintain, yes. First off, you have the problem of communication. You can chat globally in AoT, but, what if you don't want other people to hear you that arent in the clan? Theres no clanspeak available, and no systems that even support clans. When you start a clan on this game, you're basically flying blind. Starting a clan is hard, but keeping it together is VERY hard. Together meaning in unity, having people being able to respond at any time, anywhere. Then theres the money issues... You can't make a lot really fast in most cases, due to a lot of interfearance, and many people would assume being in the clan means you get all kinds of free stuff. So many variables here...
