Yes, but your K/H is way more important than kill points. Ranking #1 in K/H will get you way further than #1 in kill points.
No it will not, because 1 is 1. The score sub categories are not weighted.
Let's say, there are two players and these are their respecitve rank numbers:
K/D 1 10
K/S 50 50
K/H 10 1
Hit % 50 50
Points 50 50
Both players have the same rank number sum and would (theoretically) end up at the same total fighter rank.
It's a different matter how difficult it is to attain #1 in the different sub categories while still maintaining good enough ranks in the other ones. That's why staying alive at all costs can be very detrimental to your overall rank. But #1 is #1, no matter in which sub category.
I ranked in the top 50 flying one sortie because my K/H, K/S, and hit % were excellent. My kill points weren’t even in the top 500.
Yes, but not because the point category ain't worth much, but because you scored high in four out of five categories. In the end, it's just about the sum of all rank numbers.
I have often been in the top 10 fighters with a fairly bad k/h, because I was very good in all the other categories.
