That way you can see if someone has issues. I suggest checking back with them after fights frequently. You can read their general opinion on stuff by talking to them via the party menu. Some may still leave if they don't like your style - for example, often taking heavy losses.

There's also a chart about who's getting along, so you can have 5 (I think it was) companions that won't leave due to their issues with other companions. You can look up the "relations" of the companions on the Wiki. So thats why Leader skills should always be taken care of by the leader of the party (you) if you are thinking of making a specific companion a lord later game, then add some leadership points to him too. (If your medic companion gets knocked out, his surgery skill, wound treatment, etc skills) he wont be able to use the skills, resulting in more dead people than with him being alive the whole battle. SOME party skills cant be used, while the companion with the skill is wounded. If its a normal skill (power strike, etc) Personal skill, it only is used by that character. you can see it on the left on the PARTY menu in ( ) on the right side of the skill lists. If its a PARTY skill, everyone having that skill can add into the TOP skilled characters ability (For example, if one companion has looting skill of 8, and two characters looting skill of 5, it adds 2+ points to the TOP companions 8. If its a LEADER skill, ONLY the one leading the party will take use of it (as in you, or a companion appointed as a lord) The type of the skill can be seen on the skill menus.
