Funny, I really like both Terra and Kefka (well, the latter in a "I love to hate that bastard" kinda way), but I don't feel any urge to flame you to death. I must be a sane fan or something. ^^
And for the record, I like Celes too. There's actually no FFVI character that I don't like. But my favorite character of the FFVI cast is actually Strago. Guess I just like ridiculously powerful old mages.
