And you'll notice my sig reflects these facts
I'd like to see a weighted scoring system, where quantity directly weighs/affects the quality across the board. What I see here in AH is people flying 5-10 fighter missions, group-vulching a capped base, and getting 10:1 (randomly picked number for emphasis) kill ratios... but then they land them, and
then proceed to fly Ground Attack missions for the remainder of the tour, keeping their fighter stats frozen in the top ranks, where they then struggle to maintain 2:1 ratios.
Quality is always more important, but there's a point where you must have a quantity of quality to accurately reflect that quality.
Someone who has a 10:1 kill ratio, with 10 kills... that's not indicative of anything more than luck. Someone with 50 kills and 5 deaths... they're probably decent, but anyone can accomplish that. 250+ kills? There's a clear pattern that they're regularly killing 10 opponents for each of their deaths. I'm picking arbitrary numbers, but you get the point.
We had the same problem in Fighter Ace, so the fix was to provide sorting tiers. Kills over 1,000, kills over 10,000, etc. This helped weed out all of the posers who flew for easy kills vs. those who could actually hold their own on a regular basis.
The only "weighted" portion of the score right now is raw kills/score... and that's easy to get around. Simply compensate in another stat.
