Some balancing issues, maybe, I've noticed:
Archers can be, potentially, the strongest class, as they rely only on agility, giving at least +15 extra point. (Be sure to take Stamina though, going to need it later on.) -- To bad most of their starting skills are debuffs, or become obsolete the higher your level. (Double Shot->Triple shot->Barrage) Also, you can't compete with some of the mercs you can hire, mainly the elven ones.
Shapeshifters aren't that useful, besides as support; shutting enemies down with grapple(2) and/or lust(4+)(Note tease can be dodged) -- They take too long to set up, as you need to activate their skills one by one, and with no real damaging skills, there is no real use starting out as one.
Wizards are pretty powerful, especially in a group; early on, they have Force Bolt, Veil, and Charge to sustain them, but later they have Firestorm and Snuff Out/Erase
Warriors, I'm not too sure how to play them properly. They have some good skills, but they are all over the place. I usually use them as tanks, or as a stunner (grapple -- but you can move, so better to not start with it.) -- They can probably be pretty good with the right equip, Sword of Flame.
All in all, the best two classes to start out with is either Wizard or Archer, as the other two are better at supporting then taking out enemies.
Now then, stats:
You'll want 15 agi always, and 15 in your chosen job. You don't need the other 2 damaging moves, and constitution doesn't seem that useful, if you have good allies, and/or picked mage & veil. Willpower is iffy, as all lust base attacks are single target, can be dodge, and enemies don't seem to use Sex, meaning no real danger, as long as you're in a party, and/or take it out fast enough; if it builds up though, 4+ turns you may have trouble, as your damage will be decreased / you skip your turn.
