Basically I was just playing around with the idea of "what ragtag bunch of ships might have some funny synergies together?"
So here are my ideas:
This one works like this: you ram your U-wing against whatever happens to come towards you. Take the focus, and if something rams you, hope that you can ionize it and target lock that ship. Keyan and Roark fly behind there somewhere, not too close to each other. Prepare to unleash unholy fury upon them. Nuke the ship by boosting Heff with Roark first, then finish the job with Keyan and/or Roark. If the ship didn't die at first, but it was ionized, just reveal a 0-speed maneuver with your U-wing and repeat what you did last turn. The rest of the game might be a bit harder, but hey, if you manage to block something with the U-wing, you know what to do. Alternatively you can take anti-pursuit lasers on the U-wing, or drop the HLC for Mangler and swap Hera to C-3PO, so you can block even with the non-agility side of the Pivot Wing title.
Another list, a bit of a change for the old Rey+Miranda
So this time Heff is pretty much just a blocker that can follow up with a Conner net. Rey is... Rey.
I'm gonna try that first list as soon as possible, just for fun. They're not competitive lists, just nice lists for when you want to try something new.
Enjoy!
