I don't know if power creep is exactly the right term for it, but I think we are at risk of it with squadrons.
We've seen each wave bring in successively more rules and variations in the squadron space, and I've played a lot of games recently that were decided BY the squadron game, the ships were basically subject to what was happening in the squadron space. Not saying that's the only way games can go of course. but so much now eems to depend on timing my Raiders antisquad run right, or getting intel to Jonus so he can combo with Demo to nuke Bright Hope (yay!), or clobber jan at just the right time so Nora and her cronies are engaged so Demo can get away after..
But we have had Wave 0-1 - can ignore squads, they can't do enough damage
Wave 2 - Intel and rhymer ball but still something unreliable
Wave 3 - Flots, activations and bomber command
Wave 4 - Snipe, Nora and Jonus. Impact still to play out for Snipe, but Nora is going to be a mainstay.... And I'm losing previously undamaged ships to 4 Y wings these days!
So... I don't necessarily think anything has to be changed, but I see a risk in adding more squadron based abilities into the mix
