If we look at the Ghost/Fenn-meta you could argue that 4 TLT-shots with Ezra/Maul is overpowered but to me it is the PS11 Coordinate from Fenn that is the problem. If the Ghost is piloted by a Lothal Rebel it will reposition so you can't get into the donut which is rather small considering the Ghosts lethal rear arc would you fail the slighest. If the Ghost is piloted by Kanan you can't block it to deny it focus-tokens as Fenn will just coordinate a focus action. Add to that Fenn's ability to deny tokens spent from one enemy in arc (and with HSCP stripping Poe of his focus) and the Sheathipede's two arcs I have a suggestion. The Sheathipede gets to use either Coordinate or the rear-arc in a game, not both. Then you can still run AP-5 as a cheap support for your aces, or Ezra as a Snap-Stress but Fenn will require atleast a modicum of skill to be as useful as he is now.
Would a title for the U-wing that added the Coordinate action to the bar (without removing the possibilty to use Pivot Wing, like StarViper Mk.II works) make the U-wing viable? Or would it make Heff Tober an overpowered blocker? Or maybe the Jam action?
