What kind of builds do you think you will fly with a K-Wing in it?
FAT HAN & THE WARDEN
Warden Squadron Pilot (38)
K-Wing (23), Twin Laser Turret (6), Extra Munitions (2), Bombardier (1), Proximity Mines (3), Proximity Mines (3)
Han Solo (62)
YT-1300 (46), Predator (3), C-3PO (3), Gunner (5), Millennium Falcon (1), Engine Upgrade (4)
If you focus on Fat Han first, you're giving the Warden all the time he needs to deliver his ordnance while SLAMming past your squad. If you chase the Warden, he's dropping the bombs behind him and jumping to the other end of the map and you have to chew through 9 hit points. Fat Han is a much better closer, so I think you could fly the K-Wing anticipating your opponent's moves to be chasing Han and so placing the bombs to make the best Han chasing routes very costly.
I can't seem to come up with a realistic squad with more than 2 K-Wings (a 33 point Warden can be built that looks fun, but I don't think it's terribly practical).
What have you got?
