Corran Horn
Marksmanship
Fire Control System
R5-P9
Experimental Interface
Take a focus as your action, then Exp Int for Marksmanship(will work on both attacks), If you really need the focus for defense, then use it, but ideally you'll be able to save it for R5 regen. Attack twice with TL re-rolls on at least the second attack if not both, and have auto-focus on both attacks from marksmanship. Next turn just five straight or whatever you need to do to get out of there and get rid of that stress on the following turn as you reposition for another run. Or run someone close to him that has wingman.
Any reason this doesn't see much use? Corran is used very much, but I've never seen him like this..
