If you look at the tournament lists, you see a very diverse mix of everything, not just new ships. That right there is all you need to show that there is no power-creep.
Thats not what I see in the Regionals results thread.
Regionals suffers from being under the "ultra competitive/premiere" heading and skews results people there are trying their best to win and if there is a 1% advantage in having a given build then everyone tries for that advantage creating a much larger perceived difference than under normal circumstances
When I am looking for balance of ships ideally I would have data where player skill was even. Higher stakes tournaments are the best I can get (especially the top third/top 8) since I can assume the player skill is roughly even towards the high end. Again balance comparisons are not about popularity. Since lists often have different ships and even if they have a common ship they have different upgrades/escorts I dont think a 1% difference could be accuratly measured. I strongly think it would not be magnified such that the TIE Advanced or A-Wing were at 0% representation in the upper end of lists if the difference was so minor.
The Top 8 is still absolutely are about popularity to an extent, though. When 5 or 6 of the top 8 are, for example, Falcon lists, you have the best players playing the same lists. The only way you could reasonably use that information by itself is if they were flying 8 different lists and the same list won consistently. We're seeing the same lists win consistently but they're also the same lists making the top 8. They're obviously strong lists, but it's nowhere near proof positive that things are imbalanced.
In the midst of tournament season, I see even the best players right now going a safer route, imitating each other and only experimenting on the fringes. It's a big risk to take as the tournaments continue to ramp up, so lists will continue to stay narrow unless someone really manages to break the mold.
