After playing the .09 beta I thought the same thing which is why I started working on this mod below Emphasize capital carrier/fighter roles,
Mainly to eliminate support carriers and make capital ship carriers actually worth it. You don't see present day navies having little micro aircraft carriers running all over the place.
Now I agree you should be a good player and be prepared to balance your fleet, but the problem is, with these numbers of fighters it generates a rock paper scissors combat problem.
If you have someone that has a huge fleet of ships and tons of flack frigates and only a few support carriers with fighters, and they go up against a fleet thats all carriers with bombers, its highly likely the mixed fleet will still get destroyed.
Sure you can answer this with more carriers, but you start seeing the only answer to carriers with bombers is, well...carriers.
Problem with a huge carrier fighter fleet against huge bomber fleet is, the bombers can kill the carriers before they get destroyed by fighters, so if the fleet with bombers can destroy a few carriers of the fighter fleet, then you start seeing a tip in the bombers favor because then the bomber carriers can rebuild their squadron and slowly take out the rest of the fighter carriers. Even if the bombers are completly annilated when rebuit, if they still get one shot off, over time the bomber carriers will win.
This depends on fleet size though. 4 carriers vs 4 carriers, you won't see that much of a change. But if you are talking 20 30 carriers where bombers can destroy a carrier or 3 in one pass, the bombers will eventually win. It still takes a pass or two for the fighters to kill all the bombers. Even then the fighter fleet is now down 3 to 6 carriers and the bomber carriers are building more bombers.
Anyways this is just my two sense maybe I am wrong on a few things, but thats my experience so far.
