Every time I think about playing Vader (in the advanced), I find myself trying to buff up his maneuverability by adding an engine upgrade. Or, I try to buff his offensive punch to make up for his lack-luster two attack dice. In short, I realize that I am trying to turn him into an interceptor. Then, I just usually end up running an interceptor of my choice with PtL and call it a day.
How do other folks use him in a way that plays to his strengths rather than trying to turn him into something that he is not?
My question is a bit deeper than what combination of upgrade cards to stack onto him. What role does he fill on the table, and why is he better at it than other options?
