This combo seems really really good for the alpha. You get to select between two different targets on the initial joust due to Tarkin. Plus one of your guys can push through easy damage with their primary due to Krennic (even though Krennic is really just there so you can put Tarkin on Jendon). The only thing I'm not 100% sold on is the Adv. Slam. Without those you have 7 points to play with, but I'm not sure where the best use of those points would be. Maybe a tractor beam on Jendon or one of the gunboats and run XG-1 instead?
