Ill add a little more for #4. The reason you would boot someone is aesthetics. Their stats are 100% based on their class and level(both of which you can control), so the only difference between them is their looks(and then later, what chemistries you can draw out of them). Do you not like having lalas on your team, but had one show up among your first recruits? Kick them for the next acceptable race that applies. Is your team plain looking? Each race has 2(one male one female) recruits that come with a rare or unique glamour. If your team doesnt have a reindeer, pirate, and/or snowman on it, do you really have a good enough team? You can also do the all guys/girls, or all of the same race thing if you like. Feed them a book to get them on the class you need them on(if they didnt come with the right class to begin with), then just get them the level or 2 they ended up behind worth of exp. If you pay attention to your squad, they will spend much more time at the cap level then they ever did leveling up.
