i think we should have greater freedom in character customization. basically i noticed how some npcs have custom bodies (ie nero tol scaeva is a hyur head on a male elezen body) or how gosetsu is for all intents and purposes a human head on a roegadyn body.
i'd like to be able to make characters like that myself. some combinations wouldn't really work (ie lalafell, though perhaps they could be as tall as the shortest female aura)
in the case of particular racial features (miqote eyes and tails, elezen ears, aura tails and scales), they could be a toggle.
