Cloud didn't want to get involved->Locke was scratching at the bit.
Aeris=flower girl -> Celes is a warrior for God's sake
Tifa is a bartender -> If Terra is like anyone, it's Aeris
Kefka was crazy from day one -> Sephiroth was composed and cool from the beginning, he wouldn't have gone crazy if he (SPOILER)didn't go to Nibelheim
Shadow and Vincent, I guess are both "secret" characters you can miss out on. Plus they both have unneeded back-up storyline.

Overall I disagree
