Thanks for the replies, this is the list I have so far from you:
Abjurant Champion
Arcane Hierophant
Archmage
Argent Savant
Atavist
Beastmaster
Dragon Disciple
Exemplar
Exotic Weapon Master
Fochluchan Lyrist
Force Missile Adept
Geomancer
Harper
Horizon Walker
Kensai
Lucid Cenobite
Malconvoker
Master of Many Forms
Order of the Bow Initiate
Rage Mage
Red Wizard
Shadowdancer
Shiba Protector
Shou Disciple
Tempest
Ultimate Magus
Warchanter
Of those, I have to say its an interesting list...
Some, like the Exotic Weapon Master I find a bit underwhelming. I've frequently played PCs with exotic weapons, but I've never played an EWM. None of their abilities ever fit what I wanted my PCs to do.
Several, like the Red Wizard, I think should have been expanded into almost a template of sorts- a way to show DMs how to make their own Wizardly PrCls with style and substance.
Ditto the Abjurant Champion. I could see that being a template for different PrCls.
I'd like to add the Tattooed Monk to the list. Its not perfect, but it is one of the few PrCls that play off the relatively common trope of a being with magical tattoos. The one major change I'd make is open the class up like the Shou Disciple- letting it stack with the Monk, but not having Monk levels be a prereq.
(Footnote- I'd probably make a few other changes with any PrCl intended for use with monks, namely allowing for free multiclassing with the Monk and the PrCl, and not making Monk a prereq- just a combination of particular PC attributes- again, like the Shou Disciple.)
