What do I do now? - A new but related situation

[QuaziquestGM]

Ask the complaining player "Are you having fun?"

If he says yes, then tell him that he is worring about the "game rules" and not the game itself. The goal of the game is to have fun, not for everyone to gain XP in the same way.

Or you can argue that the multi personality character is actually getting less xp than everyone else but each personality is earning it faster due to constantatly having to deal with more difficult circumstances than the other characters. Really, everytime the guy wakes up he's in a fight!

This may be your problem. Does the barbarian have higher physical stats and lower mental ones? And is the sorcerer the opposite? Because if so, then the character is always going to shine because he's optimized for each role that he plays.

A typical multi-class character has to deal with balancing his array of statistics to satisfy the demands of each of his classes. Even with all of the other weaknesses, the ability to have an entirely new set of physical stats on demand, and be able to rage on top of that...it seems like a bit too much to me.

The barbarian should have to deal with the physical weakness of the sorceror. After all, they do share the same body. If the barbarian is stronger, it should be because of his rage, not because the body magically changes when his personality takes over. I strongly suspect that this game used either a point buy system or a fixed array for stats. Am I correct? If so, I think that this is the issue that your other players are having the toughest time with. I suggest whittling it down to one set of stats that both characters share.

Nope, we used the standard 4d6, drop the lowest method for generating stats. The multiple personality character generated 2 sets of stats to represent the 2 characters.

Changing things so that he has one set of stats is one idea. However that doesn't really seem to be what the other player is concerned about. He seems to be more bothered by the fact that, as he sees it, the other player is getting double the XP of everyone else.
