That's right Folie! Originally, Kate was going to be the leader of the group. Also, orginally, there was no Charlie character, but the Lost Powers loved Dominic and so they basically created a character just for him to be in the show.

Purely rumor, but I have read it several places (long ago when Mr. Eko's death had just occurred) that a) the actor was difficult to work with and b) one possible reason for that was that he wanted out to be able to do some directing. Take it with a grain of salt....

I almost think I can remember feeling a little different. But if I'm not the same, the next question is, Who in the world am I? Ah, that's the great puzzle!'
