There are two types of classes (that could be easily merged into one) that need to be implemented.
The first is some form of guard that uses the electrostaff. I'm constantly looting electrostaffs only to learn that neither I nor my companions can use it.
The other is a purely tech class. Have them be able to summon drones and droids, etc. You could have the advanced class be Heal, Damage and Tank, Damage.
What do you guys think?
