This is a good idea but there should be a limit of lets say 9. Three sets of formaions. I have about 4k bomber perks but i dont want to see one guy flying 60 B24s hell might as well give him a nook and be done with it. 9 is enough first 3 are free 4th would be 5 erks,5th 10,6th 25,7th 50,8th 75,9th 100. BUT you have to be atleast 9k to enable it and if you release bombs under 5K ALL you drones blow up and you loose all your perks. Unless your in a Ju88 because thats a dive bomber.
