I do not like the proffered concept. It certainly seems to a roundabout method that will add confusion.
There are several things that I have advocated for several years.
1) Place a perk value on bombs of greater weight than 500 lb or 250 kilos for all non-bomber aircraft. Let's say, 3 perks each. Perks are not expended if the pilot lands.
2) Recognize that various types of bombs were required for various targets. High explosive (HE)was typical for heavy and medium bombers attacking soft targets. Semi-armor piercing (SAP) were used against hard targets and ships. HE was not very effective against armored ships as the bombs detonated on contact and did not penetrate the vessel. SAP bombs should not be available for heavy bombers. Light and/or dive bombers would have access to SAP bombs. If HE had only 25% of the effective of SAP bombs against ships, it would greatly reduce the suicide, dive bombing buffers. Using SAP against soft targets reduces damage by 50% as the bombs penetrate deeply into the ground before exploding, thus limiting the blast effect.
3) Add some difficulty to bombsight calibration and some sort of randomizer to simulate the effect of wind on bomb patterns and accuracy. Have this tied to a multiplier related to altitude in tens of thousands of feet. Thus, accuracy is related to altitude.
4) Bombers designed for level bombing should only have bombs released by the bombardier, not the pilot. Only the bombardier should be able to open the bomb bay doors while in flight.
5) Harden barracks and ordnance bunkers. Require at least 2,000 lb of combined ordnance to destroy either.
6) Harden both unmanned and manned AA.
Incorporating the above will substantially alter the paradigm in the MA.
