Imagine Biggs had the following ability instead of his current one: "Other friendly ships that are at Range 1of you may increase their agility value by 1."
Would this be better? Sure, it's strong, esp. as it address a common problem with Rebel ships (namely low agility) but the simple solution is to kill Biggs first. Rather than FORCING enemy ships to target Biggs, with all of the game (and design)-warping issues that come along with that, Biggs increases his friend's survivability and makes himself a more tempting target. You can even play him in some of the same lists, where you try to make Biggs harder to hurt, and he accomplishes the same thing... the longer her survives, the better off his wingmen are.
Thoughts?
