I have seen 60 bombers (180 total) bail this tour when they get attacked but before I can get inside of 3k. Please increase the proxy kill range to 6k but only for bombers and let them guess if its time to bail everytime they see a dot.

Ok we can go for updating the proxy range to 6k. but lets set a limit on how long a fighter has before he attacks the buff. if you dont attack within 30 seconds when you are within 3k, then the buff will score a kill and you will die. ok j/k about that.
but to be honest lets say you attack a buff, so you will attack when you have the advantage otherwise its a suicide run. in other words you wanna make sure that if you die you at least get one kill. that's fair. so you only want to attack when you have the advantage (altitude, or pilot is busy dropping eggs, whatever), but if you dont have the advantage you wont attack. in fact u can turn around and run. or you can attack get one or two kill change your mind because you run out of ammo or whatever and leave.
isnt the fighter turning around the same as a buff augering, because he dont have the advantage of a sure, or semi-sure kill? but of course when the fighter leaves its called being smart, but if the buff pilot bails then he's a squeaker when in fact its all the same thing. which is is also the same thing as when you see a pony, 190, etc. running away from a fite and nobody calls for them to be declared a kill.
augering buffs, is just another way of saving your d/k ration or just denying somebody a kill same as when a fighter runs like hell. no difference if you really think about it.
