I've got a slight preference for no CB and no renaming - even if you're not explicitly trying to send messages to other people, different players have different techniques for renaming, which can give people away. Just hit F1 and search for the dude with three levels in fire magic.
And, just to reiterate in case someone happens to read this post but not Jurri's... Name your pretender after your nation! The pretender of Pythium should be named Pythium. I guess an alternative would be to use the game's random name creator, which wouldn't give any information either - Pasha, we need an executive decision here.
