I think so many ECVs being out there has created a lot of strange CV matchups lately.
Conventional CV1-5s are usually pretty similar. They will have plenty of pilots and their level will be roughly in line with their BO. ECVs might have anything on board- high level planes/low level planes, maybe only a couple pilots - basically what they can afford to trade for.
So with the increase of ECVs in a GB, there will be more unconventional matchups, and there will be more mismatches, and the CVs will get blamed.
For example, yesterday (in my CV4 with T3 fighters) I was biggest CV on our side. But our opponents had at least two CVs with Tier 4 fighters.
Just a couple thoughts I had from playing recently..
