[RMVX] Problem in the way I did it?

I was poking around with a new system i was trying to do. Basicly i want it to be a name/class changing system for the begging of any game i might create. (scince i usually spend a lot of time making those) So i came up with this system. The problem is, its extensive and i can't change the name of the class that i pick for the character later on.. any ideas?
