What about the fact that two people with the same score can be leagues apart in skill? For instance, let's say a K/D of 1 is the threshold to be considered somewhat skilled (and even then some great sticks are below 1). All too frequently you will have pilots with K/D ratios of 1-1.5 who are better combat pilots than those with K/D ratios of 2, 3 or even 4+. If you spend any time at all flying base defense in this game, your K/D will suffer. If you routinely stall fight better turning aircraft because you want to see how long you can last, your K/D will suffer. If you fly higher ENY aircraft, for the most part, your K/D will suffer. In other words, in order to implement your idea, you'd have to have some way to determine skill from score stats alone, but score stats tell us nothing about skill past a K/D of ~1.
