What I've come up with so far:
Warriors
Warlock
Demonology and Mimicry... So you can wield a Demonblade and an artifact weapon.

Gladiator
Polearms + Antimagic + Backstab.
Skinwalker
Swords + Mimicry.
Templar
Hafted + Stunning blows + Mindcraft.
Berserker
Axes + Dodging + Backstab.
Mages
Elementalist
The four elemental schools plus Mindcraft. No other magic, decent melee.
Mind-mage
Mindcraft and Thaumaturgy. No other magic, terrible with melee.
Battle-mage
Barehand and Thaumaturgy. Bring it on.

Priests
Hellknight
Barehand and Necromancy, for maximum splatter. Melkor's version of the Paladin.
Archers
Hunter
Bows + Mindcraft.
Sniper
Crossbows + Antimagic.
Loremasters
Shaman
Mindcraft and Mimicry. Decent melee.
Mystic
Mindcraft and Symbiosis, really bad melee. It's the shrooms, man...
Rogues
Spellsword
Sneakiness and subskills + Mana. (Yes I know, the name isn't very good.)
...
That's all for now. How do these sound so far in terms of balance?
