Vader has the biggest burst potential in the game, which requires set up. His basic has great utility (ablity block), his AOE has a slow potential AND dots. and under Palp lead is the hardest end of match one on one to kill if you can't stun him, so much healing! Vader could use a little more damage on his basic and I support a cool unique being added to give him 5 abilities but he is really good at the moment under Palp. With his Zeta, he looks to be a reasonably good leader too.
