I played this on Sunday with my bro.
One thing I couldn't figure out though. I tried creating a Yoda character, but since they don't wear armour I don't understand how you get their powers up so that you can select different skills. As far as I could tell you shouldn't waste your time with the Apprentice or Yoda and just level up the pre made characters.
Whereas I started a Nightmare guy and leveled him up, and that allowed for more and more skills/armour to be used. I am new to SC so what am I missing?
