If they let you have access to that much of the alchemy system that early, the game would be a super-cakewalk. The first couple chapters are going to be kind of boring with your classes, but once you get around chapter four the game really picks up, and in a big way.
You're being generous. I found my replay boring as
hell until I got to the end of Chapter 6.
It was nice enough the first time around since it makes clear the differences between MK and previous Atelier, which are more extensive than they seem at first blush.
