I agree that the speed of the buffs probably makes little difference in the exchange rates with fighters, it is the lethality of defensive firepower is the main point.
This slipped by me unnoticed.
In fact, it makes all the difference in the world. Even with 3 drones and 30 guns all pointing in the same place, when you run across bombers going at slower speeds (I have on many occasions run across B-17s flying at 150-200mph historic speeds in the MA), this counters all the advantages of the drone system.
If you can make any attack other than a rear attack, you WILL. One of the biggest problems in this game is that you can NOT make any attack other than a rear angle dead-6 attack on most bombers. They're flying so fast you can't even make one slashing attack before you're in chase mode and they're in front of you.
I've even dove down on B-24s with 10k alt on them and after 3 slashing attacks all my E was gone and I was chasing them dead astern. It's not a matter of positioning, luck, tactics, it's a matter of them flying so fast no matter WHAT you do you end up behind them instantly. Historically this is fubar.
When I have run across bombers flying at slower speeds I've actually taken great delight in setting up slashing attacks, being able to zoom up and dive down towards them, etc. Very much like the many reports pilots gave about attacking them in WW2. When your closure rate is 250mph you have a lot of options. When it's 30mph you have no options, period.
