So, bear with me here, but...
What if the issue is not flotillas, but the increasingly deadly direction the game is going?
Activation advantage has been a thing since the very beginning. At the very least, it was identified and exploited as a mechanic early in W2 (Clonisher), but it was only really exploited by the most deadly single activation in the game at the time, the completely pimped out Demo.
Think about it: what is it that we're trying to accomplish with activation delays? Part of it is actionable intelligence, knowing where your ships will be before I commit mine. Part of it is trying to force your ships into my threat range. Both of those considerations increase in importance as the treat presented by my ships increases. If I am very likely to kill your ship in one activation if it trundles into range of my ISD2 and Decimators, or my Yavaris B-Wings, it becomes game-winningly critical that you not let that happen.
I dunno, don't really have a point here, just sort of thinking out loud.
