UPDATE:
Okay... I've run some tests and I'm not sure what all the complaining about is concerning giving lethality to certain aircraft and how it's going to unbalance the game.
Here's the setup...
I ran two identical tests... one without and one with lethal light bombers.
In each test, I loaded up three German WWII Carriers with three squadrons of Stukas (light bombers) each (full capacity)... mind-you... in a "real world" scenario, it's likely the number may be less on availability of aircraft and/or use of fighters on carriers...
I then lined-up several British battleships and went to war.
Note, this is what I call
"The Billy Mitchell Test". These were essentially perfect conditions... there were no enemy fighters in the way... no enemy destroyers or cruisers as escorts (the Wolfshanze Mod allows Heavy Cruisers to intercept aircraft too, don't forget), I was able to attack unharrassed, with zero experienced units on either side (the ship is probably more likely to have gained experience then the aircraft).
Having said that, in the Wolfshanze Mod a BB has a strength of 42. I sent in wave after wave of Stukas... each Stuka hit for (on average) 8-points of damage when unmolested....
In test #1 (without lethal damage... as currently-is), one full carrier-load of three bombers was allowed to attack... it maxed-out at 21-points of damage inflicted (half) and the attacks were then cut-off (no more allowed). One full carrier attack was allowed, causing 50% damage to the BB, at which time the British radio'd-in that air attacks were unfair and no-longer allowed... drat... gotta finish the job with surface power...
In test #2 (with lethal damage... as proposed change), not every attack was for the full 8-points of damage... attacks continued... one full carrier... two full carriers, and finally a seventh squadron of stukas attacked from a third carrier... the first British battleship went under the waves.
Okay folks... that took two and a half carriers to sink one battleship... unmolested, without any enemy aircraft, destroyers or cruisers intercepting any incoming aircraft (plus no experience on the battleship, no damage control, no chance to get away).
I hereby declare, that if anyone thinks it's unfair for two and a half carriers full of bombers can't sink one battleship in perfect conditions, and that it is unfair to gameplay, I think you might want to reconsider your understanding of naval warfare.
I'm going to greenlight this change... I can't for the life of me figure why this would be considered unfair or game-altering by anyone... other then in a positive light.
