"If they try the Warrior -wizard thing thats all you would see"
I did not say a warrior/wizard class...I said an Enchanter/Warrior type class...like a Cleric is to a Pally, and a Necro is to a SK. The enchanter/warrior type class would have limited mind type of spells starting at lvl 9. They'd have limited mezzing abilities so you wouldnt have to rely on a bard or chanter all the time to add to your group.
As for completely original classes...I've had a few ideas: There could be a class that will rely on taking form of different animals and monsters. When you take these forms, they yield certain abilities. For example: If you take the form of a spider, you'd beable to slow, and poison your enemy. Youd get new forms as you gain levels.
