I am a Pacific War history buff, having read many books and played most board and PC Pacific War games. Having played the Coral Sea campaign a few times, I have some comments.
It appears that the air to sea combat results are too low. Most aircraft have 2, 3 or 4 CFs, so to hit, they need to roll a modified 1,2 or 3. There should be higher chances to hit for air vs naval - so there can be a decent chance of a fatal loss result, such as happened at Midway.
This also goes for naval vs naval attacks - the CFs are too low, so there is never a decisive naval battle - where many of the enemy ships were sunk, as happened to the USN in some of the surface battles off Guadalcanal.
What is worse, correct me if I am wrong, is that the defender always applies the hits, not the attacker. This means that as long as a TF with one or more CVs, has some throwaway ships like DDs and CLs to take the hits, it is impossible to hit or sink a CV, by air or naval attack. In real lie, the attacker picked the targets for attacks - such as naval air targeting CVs in a TF, rather than DDs.
Similarly, enough DD and CL units can always soak up all hits in surface battles, in lieu of the hits being applied to the more valuable BB and CA units.
Even an option to randomize the hits to be applied to the defenders air, ground and naval units,would be preferable to the defender always being able to choose the least effective unit to take a hit.
Otherwise, this is an outstanding scenario for WAW.
Can these two game aspects be edited in the Game Editor?
