I have all 4 tier 8 premium CVs and I like to play them but CVs needed some kind of nerf and AA made more relevant.
The only problem I have seen so far with this change is with Saipan. It already has very few planes and I found myself, for the first time since I've got it, without planes towards the middle/end of the battle. Although it has tier 10 planes, the planes are still destroyed one by one even by lower tier ships. I think Saipan will be really underperforming compared to the other CVs.
Maybe consider giving it (or even all CVs) faster regenerating time for planes?
I really liked Saipan until now. It needs a fix in some way.
