You and me both, bro.
The fact that some banana in a La7, Tempest, P51D, Spitfire Mk XVI, F4U, or other such easy mode plane gets the same score as someone who gets kills in a P40x, P47x, 109G, 190, or other such plane with a much smaller tool belt is very misleading. I don't know how HTC would do it, but linking the plane to the ranking system would shake things up in a major way. We'd see a huge shift in which planes seen in the virtual skies of AH, the score hoars would have to up in a 20+ and 30+ ENY aircraft from time to time in order to keep their rank.
Ultimately, I think the ranking system should be thrown out anyways. If anything, figure out how to tie perks earned to rank. Then that fellow flying the P40, zeke, etc, would get their due. As will the fellow flying the Boston III, He111, G4M, B25, etc. As it is, the Lgay, P51D, other such easy mode plane circle jerk will continue. Sad it is.
