Hey folks. I started playing a few months ago, but haven't gotten too many games in due to work schedule. I've collected all the models and have a decent Imperial fleet. My opponent usually fields Luke/Wedge/Biggs and I like running all the named Ties so I can get better at dog fighting and flying in formation. I usually get creamed pretty badly although once I won by crowding Luke off of the board.
Luke is usually the last guy left since he's always got R2-D2 and is impossible to kill without Wedge tearing me a new one. Once Luke is left, I'm usually down to one ship and it becomes impossible to kill him without him flying into asteroids intentionally.
So I ask you sages of X-Wing: How do you kill Luke? Am I doing it totally wrong by prioritizing Wedge before Luke? Is there a trick to nuking Luke before he just goes Green and gets his shields back?
