I still tend to think its a minority of people that get into the politics thing, it's just seems to get others wound up as well, then mates support mates and before you know it there's a bun fight of epic scale going on..
The whole 7th man problem happens even in splinter guilds (and guilds that have nothing to do with CUK at all). It's not a CUK thing and writing off CUK as in in game guild wouldn't solve that problem..
Just to put things into perspective, for longer than I care to remember going back over playing games (and in fact the odd RL PnP RPG) this isn't a solely CUK problem. Almost every guild of more than 6 people seems to have splits, bust ups, arguments, reconciliations etc, just take a look at almost any large guilds forums.
Until guilds start doing psycometric testing and personality profiling before letting people into very small tightly controlled guilds this will carry on happening.
Strangely enough, and contrary to my complaints in a former MMG, I'm starting to believe the only way a guild will hold together in a game is for it to have a very strong leadership of GM and officers with clear and enforcable rules, expectations and code of play. In (brace yourselves) EQ Unny was a very good example of how to do this (although it drove him to dispair). Unny respected and listened to the guild and officers, but ultimately it was not a democracy, because he held the respect of the vast majority was able to make the final decision about things with no ifs buts or maybes.
At least that way the members know where they stand, what the rules are, everyone has equal rights and opportunities and ulimately if it's not your style of guild you option is to join a guild that suits your play style rather than launch a revolution
In CUK I guess part of the problem is there is no "leadership" and rules as such beyond Roch on the forums, so every in game guild ends up with some poor bugger nominated as GM who then has no real authority to do anything other than get whinged at
Just thinking out loud here.. feel free to shoot me down in flames
