henrique, I think you identified a real problem without realizing it....the targets you killed came up slowly behind you. If attackers use a better strategy, bombers can be almost helpless...and even with things as they are, bombers die roughly 3 times for every time they get a kill.
Honestly, I dont think anything should be done to further weaken bombers' chances -- and I'm speaking as someone who attacks them, not someone who flies them!
