I get your point about predator being important, I'm actually considering lone Wolf instead though.
I played a Kenkirk build with Palpatine, Ysanne and Determination on Wednesday and after it lost its Shields it became incredibly difficult to hurt. Determination came into play once or twice which was great, but I suppose I am using an EPT slot for an 8/33 chance of stopping damage.... Which actually isn't that bad an odd.
I'm thinking that without Darth Vader crew decent rerolls would probably be quite important in trying to punch through Soontir et als green dice to. Hmm
