Bomb craters just forced everyone to just take off into the surrounding fields around the airfield.
I never used the runway when bomb craters were enabled, most of the time (unless you were landing) you couldn't see them until it was too late.
We need to encourage gameplay not because of historical reasons, but in spite of it. Do you want to fly an 8 hour mission with less than 30 minutes of actual combat? Unless it is a scenario type environment, I sure as heck don't.
I like the CV idea, might help immersion and doesn't negate good gameplay. I'd go as E25280 said and increase the durability of the CV, but I'd recommend about 30% only.
