This isn't WWII though
It's a computer game
There are always people that will do whatever lame stuff they can get away with in computer games. Many different examples of this in AH...and it's never going to change
And wouldn't it be great is by attacking empty bombers you could actually impact strats some how. I mean, by killing bombers early on germany hurt both the RAF and US Army Airforces by killing the bomber faster then they could be supplied, and it impacted how the war was fought. we can not do that in this game. There is an endless supply of bombers , killing the aircraft has no impact.
