I didn't see a forum post about this yet so....
edit: just the name change part
I like blue mage, remember the steal the spell cast on you mage that is a cool game mechanic and i think would fun to be implemented. That kinda spell would fit with the thaumaturge style i think and i just like the name blue mage.
A conjurer is like a black mage and a white mage had a baby and compromised on the name conjurer and honestly conjurer is connotative of like conjuring spirits, apparitions or summons and less "just magic". Other names that could be used though are maybe grey mage or Gandolf...
what names would everyone else like to see
