This is one of the biggest pet peeves I have about AH2, that being the hyper-accurate BUFFS. But, realistically, if the wind was turned on in the MA, this would all go away.
The ability of one set of bombers to hit a moving CV from 10,000 feet is wildly out of sync with reality.
There are a lot of factors making it ridiculously easy compared to R\the RL war, most of which have been mentioned:
* Easy calibration and hyper-accurate bombsights
* Perfect and uniform ballistics for bombs
* No wind, turbulence, haze, clouds, smoke, or other variations in atmospheric conditions
* Target often not maneuvering
* Targets always move at the same speed and are always the same size (making lead calculation easy)
* Lack of fighter opposition
* Ineffective AA
* Relatively low alt bombing made possible by the previous two factors
OTOH we use CVs in ways that in no way resemble anything that would have been done with them in WW2. Even having (invisible) transports and cruisers getting as close to the beach as our ships routinely do is ahistorical. There's also no need to turn CVs into the wind for flight ops, which is HUGE advantage.
My pet nitpick: why don't our destroyers have long-range torps? That would certainly discourage passing opposing TFs right through each other.
