MMO Style Classes (Old dravic race system)

Changing main post to show the current classes, and what im looking for with suggestions

Hello I was thinking about the ranger class and I have a suggestion. The jump boost is only a little so you can't even jump 2 blocks which essentially makes it useless since you don't have to jump 1 and a half blocks a lot. Or get rid of the jump boost and increase the speed since there isn't a lot of classes that increase speed by alot. Just my idears.

Do you know if it's possible to add effects from eating? I had the idea of a Slime ( :3 ) class that changes size based on either how often you eat or how full the hunger bar is.

Sorry nope. Maybe in bukkit or FTB, but other than that no dice.
