Not sure if suggestion or just a request, but it will be added to over time, after finding more examples.
I will provide BR, Fighter and Bomber name in game and Map each time.
Hoping Devs will adjust their reaction to make bombers defend themselves a not better.
Let me add my first lot after today’s event grind, feel free to add own, please do provide, BR, map and plane info.
Did not shoot:
BR3 Axis - FW190 A8 Vs AR-2
Your first note is interesting given the A8 is one of the best planes next to hispano and 30mm bearing planes for shooting down bombers… i think it’s fitting if you want to make such a crusade to include clips of this instead of going off pure heresay
Some of them also just have less gunners… in odd places or you’re in their blind spot.
Making them harder to kill won’t fix the inherent problem of them taking too long and doing too little damage.
I propose… if you’re so adamant on wasting team resources you also waste your own time to ensure their survival… have an option to pilot the gunners yourself switching planes and gunners alike.
Frankly these need a complete rework or removal from the game… not some patchwork that only serves to make their only good purpose which is point farming harder to do.
I think it won’t be a waste of resources, I would imagine it is just a list of what planes and faction are and aren’t enemy.
Beside bomber farming is easy xp, I think it should be a challenge, not just see them fly towards and profit.
It is my time and in my opinion not a waste, we all have different reasons we play the game, I support this project and have over 8.8k hours, so if you don’t mind, it’s my choice to do this, I stead of critique you could give examples yourself 
Long time ago, I noticed that the Ju-88 gunners never shoot.
No matter which aircraft I’m flying in.
I’m not sure which map they appear in, or what makes the bombers Ju-88 or He-111 for example.
Anyway, when I see that the bomber raid is Ju-88’s, I can just take them all out without them firing a single shot at me.
Yes, if you can make a note of planes and bomber and BR it might help, I’ll be compiling a list, but not a guarantee bombers spawn free lane slot, so may take time any support with this would be appreciated.
The different bombers are related to the radio squads, so if Italian radio ops, then Italian bombers can spawn
