Two suggestions:
1) Make their guns indestructible. The reason is that the dweeb dieing 10 times trying to kill a CV gets unlimited lives and tries. The CV does not get unlimited gun "lives". Therefore, after strafing a cv X number of times, it is rendered defenseless. Once a single guy decides to target a CV, it is all over. Lets even the playing field. If they can keep upping new planes, let the CV keep its guns.
2) Make the ack around CVs actually useful. Right now someone can pick you with the 5" 5K out if you are in a fighter, but if two sets of buffs come in from different angles you don't have enough time to react. The 40and 20mm guns are useless. Low over the water buffs can get to the CV on time to drop a few times until its dead. Who knows, it may actually allow the guys upping from it also get some alt before they die.
Since some of you that like the easy mode will come back with the if you don;t like it defend your CV, I ll answer it now. You can't defend it for the above reasons. Not to mention that guys go out to sink them when no one is around. There is no way a single guy should be able to get close to a CV group.
