Currently, there is little incentive to fly 1h to get to the best protected target in game. Neither in effect on gameplay, nor in score. (When the strats where redesigned there were a lot of remarks like "Now you milkers have to FIGHT" - No, we do not. We just have switched targets, in some way milking is easier than ever before. Bombing a few towns gives you more bang for buck than trying to hit the ack & Me 163 infested city target.).
My proposal:
- Keep the new strats, but make them worth more. Give them an incentive to fly 1h across the enemy airspace. Score ain't the worst one for that.
- In place of old strats, add some
railyards (and reintroduce the old zones) Let them have some mild supply modifier for all corresponding bases. That way medium bombers will have targets again, enemy bomber missions are not that predictable anymore, and there may be the old "ZONE BASE UNDER ATTACK!" cry again

Also railyards are really a thing that's missing from a premier WW2 combat experience!
