And what would they do with the 3 feats they'd have over a Fighter 6?I dunno, I don't want to be the DM that says you can multiclass like that. Could you imagine if someone took Feat Rogue 2/Fighter 2/Psychic Warrior 2? A human with two flaws would have 12 feats at 6th level.

You've also forgotten to take account the XP penalty the multiclassed character will probably incur.

In 3.5, a Human with 2 levels in 3 classes will soon find himself facing XP penalties as he levels up, iirc, due to the difference in levels between his various classes.No xp penalty, he's human, or is it different in Pathfinder?
