There was full manual calibration in the MA and we saw the results. Wind, bomb dispersion and things that make level bombing less effective lead to only one thing - dive bombing lancasters/B17s. Unless some mechanism that prevents heavy bombers from dive bombing (bomb release from F6 view, restriction on dive angle for release, etc.) is installed, this will happen again.
2 wrongs do not make a right IMO.
I would welcome full manual calibration, windage etc regardless of what ever fix may reduce the "missuse" of of heavy bombers. I would equally welcome a fix re the "misuse" of heavy bombers regardless of what ever fix may reduce the use of easymode level bombing.
As it is a game then (IMO) both could be available but with a penalty of some sort (higher random drift? 50% lethality?) applied to easy mode calibration.
