For what it's worth, I know Dropbear was rather unhappy with the crew/NPC death numbers and very much wanted to do something about them, so it's not something that CCP is unaware of.
That said, I have to point out something about this quote (bolding mine):
And what is wrong with numbers? Reasonably speaking, on a day where I sit down and seriously rat (running a tengu/blaster Naga dual box) I generally say that I will rat to half a billion isk. This means that my little two man fleet, kills maybe 350 Serpentis battleships. That's not an insane number. I never claimed that I personally killed thousands of battleships a day, but that across Fade (a whole region where there are a ton of Serps) 42(ish) thousand ships were killed in a 48 hour period by all the capsuleers living there. How many trillions of people are there in New Eden? The current death rate of the world is roughly 153 thousand a day with a population of 6 billion. That ratio with a population of 50 trillion yields 1.275 billion dead per day. Sooooo, why is killing 5 million people every couple of days across a whole region of space breaking immersion?
I think the math is a bit off here: Assuming a roughly 38% survivor rate - towards the high end of what EVElopedia tells us will survive a battleship - from the very lowest possible crew aboard each Vindicator hull, 2,500 people are dieing from each kill.
Let's be conservative here and, from the above post, say you only kill 200 BS. That's 500,000 people from you, alone, in a single day. Now, I asked Alizabeth last night how many people ratted in Fade; her answer was 2-300, maybe more. Again, let's be conservative and say it's only 200. So,
2500 * 200 * 200 = One hundred million. Admittedly, these are very rough and very simplified mathematics, but still - one hundred million dead every single day from battleship NPC kills alone in a single region, not counting losses of any other type of NPC rat, with conservative estimates.
It could easily be far, far higher, assuming that number of crew don't always escape or there are more people ratting harder.
