Ever wonder if HTC changes the weight of the categories from time to time without mentioning it? I'm mean really, the entire scoring, ranking, and perk system is based off arbitrary numbers that HTC can change when and how they see fit.
It is no secret the it is not "how" a kill is earned only that it occurs. That is too bad, really. For a person who lands 10 kills in a P40N should in theory be a more "skilled" pilot than a person who does the same in a P51D, and hence should have a higher than typical score or ranking. Take a look at Bong and his P38 vs the early and mid war pilots from Japan, vs Preddy and his P51D and his victories vs late war Luftwaffe pilots. Who had to work harder and who had more of a challenge? For the record, I'm not taking away anything from anyone as they all deserve our respect, but like in AH it does not matter what plane they flew or what the enemy was flying or even the ability of the enemy pilots, all that matters is the "kills". HTC compensates players for using high ENY aircraft (P40x, 109Gx, etc) by awarding perk points but ultimately that means nothing in terms of ranking or scoring.
To achieve a high rank or score in fighters, it is all about maximizing your ability to get guns on as many targets as possible without letting guns get on you. Hence, why the LW server will never see someone in the high ranking places using less than 5-10 ENY planes. As Looshy said, 3/4th's of his kills were bombers. Do you think he used anything but 163's, Ta152's, Me262's, Me410's, or other such prime bomber killers??? I dont even have to look up his stats and I can tell you that. Do you think he took up a P40x, or a P39, or how about a 109G-6 to round out his fighter score??? Go ahead and look and report back.
Learn the scoring system, exploit the best way to achieve it, and go to it.

It would be nice if HTC had a way of sorting out the ranking system a bit further to award "Best Luftwaffe Fighter Pilot", or "Best Japanese Bomber Pilot", or "Best RAF OBJ Attacker", etc, etc. Yeah, there would be 20 different "best" categories of all listings were used (4 categories w/ 5 countries), but it might make it worth while to pay attention to what people used as a platform to get the job done.
