On another thread, a poster suggested the option of letting players rename classes. I thought it might be interesting to see what custom names people would pick.
Warrior monks can be really interesting. Tendai Buddhism had an army of warrior monks, and the idea of Buddhist monk fighters has an appealing paradoxical air. But I can't shake the association of "monk" with "peaceful monastery dweller," so I'd rename them. Perhaps "hermetist," since there's something to their mechanic that fits one definition, "impervious to external influence", though there's no real connection to hermeticism. It doesn't fit perfectly, but "hermetist" is just a funny word.
On that note, I'd work in "theurgist" too. Maybe the clerics.
I'd probably change the names up on different playthroughs.
