What would be your 6 to 12 casters?
Different person but I listed 17 several pages ago.
Arcane gets wizard and artificer,
divine gets cleric (white mage really) and paladin,
primal gets druid and beastmaster ranger and warden/primal barbarian,
dragon magic gets sorcerer and dragoon,
fiendish magic gets warlock and hexblade,
wild magic gets wild mage,
shadow magic gets shadowcaster,
rune magic gets runesmith.
Bards either get their own kind of magic or the ability to dabble in multiple other types.
Qi gets the mystic and monk.
I'm lumping psion in with monk here, and I had forgotten about elementalists (sha'ir and a warrior type) entirely. And yes, I have slightly different mechanical implementations in mind, though a lot of that comes from only using "spell slots" for arcane magic.
It's not that hard to come up with a lot of different ways to fantasy; the hard part is keeping it from getting out of hand.
I'm back to four: fighter, wizard, thief, bard. If you need something other than that, multi-class or use the sufficient skill system, or grab a feat. That would make the D&D Monk a kind of "thief" tho. Maybe: knight, athlete, wizard, and bard?
