Ce is like Dr with better equipment options and innate swiftness in return for (mostly) worse aptitudes, which sounds like a good trade given how much XP there is in the game, but it still kind of sucks because you have to play Ce.
Fe is cool because it looks like it sucks at first but it's actually really great, what with the extra lives and movespeed and awesome stealth. Low HP doesn't matter too much if stuff can't actually kill you, and only Sp can pick their fights better.
Gr's low HP hurts more than Sp/Fe/VS because Gr doesn't have move speed to get out of early trouble nor spirit shield+mana drain to give a secret bigger HP pool, and their AC doesn't do much about orc priest smiting or early ogres. But hey, at least they aren't Te.
Then again, I like Na even though they're pretty bad to start, so whatever
