Well, the problem with that is that none of the nuns seemed to heal you, ever, Barbarians can be both Class AND Race, depending on how you look at it, as at one point of time in history, they were a race of people, a tribe, and only became a kind of 'class' when the life style of the tribe/race became appealing to other people.
I guess my problem with it is that it doesn't hold true to Chrono Trigger or Spekkio, who creates the classes in the games. They didn't have classes there based on what weapon they held, like in other games. The weapons they held were because that's what they were accustomed to using, not because they had been trained in them.
I mean, it was just a suggestion on my part. I'm not even working on the project, so whatever you guys decide is up to you. If it sounds good to you, do it. I'm probably just a small minority, anyway. You do lose the uniqueness of the MMO if you go with what you propose, though, and it seems to me like being lazy about designing brand new classes based on what CT actually provides.
