I didn't really like the ranks of the clans. I didn't mind doing them, but they should be just fun... no guests, but not ranked. If you want to play a clan match for bragging rights, then it should just be tallied or something, similar to Clan Compete.
I do think that what they should do with the clan list is give the overlord an option on making new clan ranks, though... like how we have peon, member, staff, and overlord, I think that there should be more. You should be able to create your own, and choose all the options that the positions would get... that's just my suggestion because that's what WoW guilds did. The guild leader got to create new ranks, but only a certain number of them. The reason that I think this would be a good idea is it would give people a chance to do more when they're sergeant, or more when they're lieutenant. Because there are some people that keep complaining thinking that they should get the option to do what captains and generals, or higher do. And I'll agree that Captains and above should be the only ones limited to that stuff, but I do think that if there was a way to give them more ranks, and more options, then it would seem a lot more fair.
Although things have been working great how they are right now.
