At this point, I think FFG is just playing to the fan base of some of the shows. That dial for the Shadow Caster is just wrong. It's got a better freaking dial than a TIE Fighter . You know, that ship purpose built to be insanely agile and maneuverable?
And seriously, the Shadow Caster can make a white hard 2 but the Defender's hard 2 is a red? The only way any of this makes sense is if the design team is trying to say, "Look kids, it's your favorite ship from the TV shows! And it's got an insane dial and abilities, buy a bunch of them NOW!!!"
