Rot, it's near impossible to intentionally ram and give damage and not receive damage due to unknown lag differences. Since planes are free and nobody really dies, intentional rams would increase if both took damage every time. Dweebs will be dweebs.
I know, I stated that; that if someone tries to ram they will get damage if they succeed. I'm not saying both should take damage.
What I'm saying is bombers, unless you are 999/Snail, are at a pretty good disadvantage. What happens is a guy comes in full bore, pulls away at last second, his angle was to high/speed to great for gunner to track him, bomber gets a collision on his end, ftr doesn't. The bomber can't do anything about it, why should he get the damage?
