From what I read on your characters view on tribal life, I think it'd be a blast if my character met yours. You'd blow his mind and make him think really hard on the things he was taught as a kid.
On another note, if people are less inclined to change their names, how about a off-shoot tribe from the usual tribes, one consisting of Miqo'te who might have left their original tribes for a reason but still feel the pull to stay connected to other tribal miqo'te?
I'm usually on as L'ohke Tia, and I sure don't mind being added as a friend for Viper tribe hijinks..I've yet to actually spot other L'members in-game.
To add to the whole conversation though, I've rp-ed with several Tia's from different tribes now, and all of us have very distintive and different personalities and views on the Tia and Nunh, and how males should act. It makes for hilarity more than conflict, so I don't really see any trouble in people adopting their own 'facts'.
Heck, I basically play my off-shot off the L'tribe based on elfquest!
