Here are the favored classes IMC:
Grey Elves: Elementalist (wu jen with a retooled spell list)
► IMC, they are mariners, loving nothing more than the freedom one has on the open seas. Not the aloof-snob-midly racist mountainers archetype described in the MM. I liked a magic favored class for them, but wanted it to be more in-tune with a chaotic good race, and the wu jen is just that -- a chaotic wizard in better tune with nature.
High Elves: Hexblade
► Those, on the other hand, are definitely aloof and upnose-looking. They love to fight, and to fight dirty. They develop magical powers too, but only secondarily. They are bastard at heart, use their curses as oppression tools. A chaotic evil culture, although of all, the most likely to produce lawful members.
Wood Elves: Scout
► Wild and unpredictable, the chaotic neutral wood elves can be friendly and hospitable, or hostile and aggressive. One never knows, upon entering their forest, if they'll be welcomed to partake in their bawdy celebrations or hunted to death just for trespassing. It is usually possible, in the case of a wild hunt, to negociate with them, but that usually involves besting their master of the hunt in unarmed combat.
