Would you then be able to start out the new jobs from character creation? Everyone else is common lancer/sword person/basic mage, then there's this dude with a soulstone... After all, anything added won't have a class but go straight into job. That's lorewise kinda what's referred when our senior characters pick up that new tool and soulstone, we have the experience and promise through other thing.

I also don't see a point in starting at 1. You won't even learn skill by skill, as their usage and traits changes on the way up, making you trash whatever was learned. There's no learning rotation bit by bit, because there's no rotation.
