I liked how different squadmates were on different points on the "Lawful-Thug" scale, and how your personality (Paragon-Renegade) could sway them, but not to an extreme.
Paragon-Shep can influence Jack to be a bit nicer and leave her "look out for #1" mentality behind, but she's still "JACK", still rough around the edges.
They remain their own characters, but they also mirror Shepard to a degree.
I like that. It gives the choice of how you treat them some weight, your choice of demeanor has an effect on them.
So I'd honestly prefer a "goody-two-shoes" squad (I don't want to worry about being stabbed in the back by an "outlaw" or worry about them jeopardizing the mission), because half the time I'm there to SOLVE problems caused by "outlaws", sometimes by the very "outlaw" I've brought with me.
Don't get me wrong, it's interesting and makes for good roleplaying/gameplay, but sometimes it would be nice to have someone who ISN'T a wanted criminal or a potty-mouth or some such.
I'm all for having an "anti-hero", but you need a real "hero" to counterbalance, otherwise you get red-n-black all over and it hurts the eyes.
All said, I think Andromeda's squadmates are gonna be fun, interesting, and cool to have around.
