Hya mtnman,
As you said:
Cause: You improve %hit
Effect: You improve K/D, K/S and K/T
I agree with that statement but,
Concerning to the ranking, it should only recflect the final results (K/d, K/s.....) and not the tools you use to get the results (% hit)
Concerning the fuel amount I admit it is an exemple taken to an extreme in order to express my thoughts.
The best your %hit is, the best your K/d and K/s could be.
The havier the plane you you are able to control in a fight (full of fuel) , the best k/d and k/s could be.
(I'm trying my best with my english level Sir
