So the Instigator title on a Raider reads that enemy squadrons at distance 1 are treated as though they are engaged by 2 additional squadrons. Suppose I fly my Instigator into range 1 of 2 of your X-Wings. And also suppose I have a Star Destroyer on the other side of the X-Wings, also at range 1 of them.
Initially I thought it would force the X-Wings to fight the Raider.... but It doesn't say they are engaged WITH the Raider.... just that they are engaged. If I have no squadrons for them to shoot at, can they still shoot the Star Destroyer? I would assume in this case they could shoot whomever they want, but they just can't MOVE.
