So, I'm thinking of trying out a list pretty soon that I thought up a while back. It's nowhere near as powerful as 4 Gamma Veterans will be once Imperial Veterans comes out, but I feel like it's a decent enough stop-gap until then:
Captain Jonus - Deadeye, Proton Torpedoes, Extra Munitions, Guidance Chips - 29 points
Major Rhymer - Deadeye, Proton Torpedoes, Extra Munitions, Guidance Chips - 33 points
Redline - Fire Control Systems, Proton Torpedoes, Extra Munitions, Guidance Chips - 35 points
Total - 97 points. Three left to play around with. Swapping out Protons for something else, or just adding a missile to one of them. This list has pretty much the same firepower as the Jumpmasters, higher pilot skill, and Bombers are tanky enough that it will take at least two Jumpmasters using their ordinance to blow up a Bomber. Redline might have trouble getting his target lock against higher pilot skill aces, but the other two get Deadeye, at least.
So, without using anything that hasn't been released yet, how would you change this squad to better combat Jumpmasters? For the record, yes, I know Carnor Jax and Crack Squadron Pilots and Imp Aces are all better Imperial counters. I'm trying to play around with ordinance, so please leave those out of your suggestions.
