A Chemist was basically a use button. It would be an interesting class. Particularly because right now it is so hard to use poitions and such in battle. If a chemist class had a use button and could throw a variety of potions doing various stuff it would be something different.

Also I would like to see Con split into a healer and a DD. I think then you can do what is currently needed and make the classes different from each other. I would also like sentinal to be its own class. If you have a sheild you become a sentinal. Also turn Glad into Samurai.
