Remember that CV balance is based on ship tier first, then BO level. So if you have a
level 90 BO on an essex but only level 80 fighters you will be considered a higher ship
then a level 80 essex with level 90 fighters.

US forum always helping out.

Theoretically it doesn't really hurt so long as you use the proper equipment on your
ship; that is, you don't try to run T1's on your Yorktown. But as a general rule of thumb,
having better crews than your BO reduces the temptation of doing as such.

You may also want to raise at least one more fighter and a few DB pilots for flexibility.
There's nothing wrong with having four fighter pilots, but raising more than that gives
you tactical flexibility since you can swap your setup around whenever you want; run
fighter-heavy and keep the enemy team blind, or bomber-heavy and kill ships, or
whatever.

I HAVE A PCV WITH LOCAL FIGHTERS!!!! I´m DOING THIS RIGHT?

the same thing applies to CV, you dont want your pilots to be lower level than your
BO...if you're in a cv4, ppl expect (and the game balances) you as a cv4...if your
pilots arent cv4 level, you're going to be a hinderance to your team
