I think everyone is missing the point though. We can't just sit and compare plane X with Y, in AH the "average" bar is set currently at the La7/P-51D/190D9/etc level. There is a set of 5% of the aircraft that are perked that are marginally better than "Average", the 5% in this "average" group, and 90% that are below average, some significantly. The typical AH player is no ace and can't rely solely on skill/ability to get a kill, he has to pull in situation, altitude and aircraft performance considerations, thus he will pick at least the "Average" aircraft so as not to penalize himself. It's also why some new aircraft, unless shown clearly superior in ability to this "average" that's been set, won't ever really see any significant use in the game. There will always be guys looking to try some other ride out, those with some personal historical significance, or those who really want some extra challenge who will fly other rides, but the typical player would simply be putting themselves behind the 8-ball in doing that. Even of the players acknowledged as "good", many of them still fly one of the top aircraft most of the time.
The only way to change that is to lower the bar on average and unless HT/Pyro make an effort to do that then the situation is unlikely to change in the MA. It's shame though, there are so many aircraft with so much character that simply aren't that competitive in the game but would be an absolute blast if they were. It wouldn't have to cripple the game to lower the bar, the C-Hog experience showed how a low-cost perk both balanced usage but left an aircraft accessible to typical players (the C-Hog still gets good kill totals and deaths each month, risking the 8 perk points isn't really an issue for anyone). It would mean that a lot of players who rely on the uber-late-war-rides would find themselves out of their primary/secondary rides though and that's unlikely to be popular. All it takes is the current side-balancer to see what happens when a bunch of guys who don't know anything but these top couple of aircraft get stuck in 190A5's or 109G2's, it's not pretty.
