Final Fantasy Hacktics

I wish that Frimelda, Vaan, Adelle... not be humes. Not saying all should change, just that for instance, I like to play with special units only, I get a bangaa, 2 humes, a moogle, another hume, a viera, another hume, a moogle, aaaand another hume.... the last hume cannot even change jobs... he stayed an agent...
