If those fighters are good, I'd hate to be limited to 2. At the same time, I have no need to drop yet another $50 for another ISD (with most of us having 1 if not 2 or more already).
I hope this doesn't become common (2 U's in with the Profundity, or a single fighter with each small ship, or something like that) . I hope these fighters aren't super powerful and efficient enough that I'd want more than 2 in my builds.
If they throw them into a fighter pack in the future, no harm no foul. All the odd combinations and hiding useful ships or upgrades in epic ships in X-Wing always rubbed me the wrong way. I hope Armada isn't moving in that direction.
