Considering there really wasn't much choice and most of the girls in SO3 were useless (hellooooo? Why do I get two Lv. 1 characters when I'm around Lv. 40?) that's to be expected. Of course you always have to pick favourites if the game doesn't share experience among your entire party (like, say, Tales) or at least autolevels the characters that are dragging behind (Anachronox would often raise the level of all characters that were falling behind when you progressed the story) so characters that start useless often remain useless.
