Atlantico: How do characters more involved with combat get more XP than others who are less involved with combat?
A solo character will advance at the same speed as characters in a larger team.
Sufyan: A kill awards immediate XP to the killer, then after the fight the whole party gets the appropriate amount of XP for every kill, so double XP for the killer.
No. There is no "immediate" XP reward after a kill. Go check it out.
When an enemy is killed, the "XP" that floats over it is not received by anyone, it just indicates the XP that kill will give all characters at the end of the fight.
So, no double XP for killing.

hedwards: That's what I was getting at. I'm sure it's not enough to make up for the loss of the other parties, but a single character will advance more quickly than any one particular character out of the party.
And you'd be correct if a character received extra XP for being the one who made the kill - but it isn't like that. Which was my point.
Again, go check it out in-game. No extra XP received for the character who made the kill, just XP at the end (even though there is a "floating" XP message after a kill, it doesn't give anyone any XP) and everyone gets the exact same amount, no matter how many are in the group.
