I'm thinking now that, while I do love the idea of promoting loyalty and collaboration (I may be a square, but I have a hippie heart hehe), is it right to "force" it (I know the word is strong, but I couldn't find a better one) on guilds that don't care about it?
I mean, when Don Boba said "Needing to kick someone is a penalty by itself.", I thought that "needing to kick" is relative. But shouldn't this be something for only the GM to decide? Even if he decides everyone in the guild should decide together, wouldn't that ultimately be their decision anyway?
Playing the devil's advocate here, I can see someone being angry because they want a top-performing guild with many people being exchanged whenever needed, but their play style (although one I don't agree with) would put them at a disadvantage facing other guilds (which could make a significant difference in the upcoming guild wars).
But, again, I would support the ideas I mentioned on the other replies and what I argue here is not my personal opinion. Just trying to present a different point of view.
