I would like to see a Droid class.
You can be one of the droids from the factory that get miss shipped or ends up in an event that leads to you starting your class's quest. They can have one for the Sith and one for the Republic.
The droid would be some humanoid type of droid. You can customize yourself into a battle droid with heavy fire power or a droid with light weight which will allow you to use blades and maybe even a lightsaber.
