When going through the character gen, I made a "Thoughormtere" uhmm.. blackmage. But, I wanted to make a White Mage. The starting Char Gen dint say " hey, this guy here is a healer and this guy over here shoots fire!!"

..did having my character start as a Blackmage change my basic stats? or can I just switch to a whitemage weapon to become a conjurer?
I know.. Newbi question.. but I am a newbi.
