Reduce number of top tier carrier in low tier

[Krakens_Slayer]

I have been experiencing a lot of game which have 2 tier VIII carriers in a VI ,VII and VIII match up. No matter how close we are, our AA combine can't do anything. Low tier cruisers and destroyers with weak AA suffer the most, a decent tier VIII carrier player can easily kill them with just 1 or 2 rocket or dive bomber squad . Every games in low tier with 2 carriers as top tier , all surface ships get wiped out and what left is just 2 carrier each team striking each other. Low tier ship suffer when being up tier is a normal thing, but having 2 carriers as top tier is just unplayable and helpless.
