Granted, when one plane constitutes 20% or more of the arena usage it will be perked according to HTC's guidelines.
However, my point is that the guidelines should change. There was a thread several weeks (maybe even a month or so ago) that had the plane usage and highlighted various planes.
Of the planes I mentioned, two of them held almost 20% of the kills (together) in the MA for a single tour. Think it was last tour. P51D and N1K2-J. The La-7 held 7.4% of the total arena kills.
The 109G10 and 190D9 are naturally not as popular, however when you look at their brethren then you see that it's basically "grab the bestest latest ride"..
The 190D9 had 3.88% and the 109G10 had 3.47%.
The 190A5 and A8 (F8 excluded since it's a Jabo) had 2.76%... combined.
The 109G2, F4 and G6 had 2.45% combined. I excluded the E4 because I don't know if it was in for the whole tour.
The chart is in this thread:

However, when you look at these statistics it's obvious that making them low perk point rides (2-3 perk points, c'mon you can get that in one flight!) would up the usage in the MUCH less used variants and would bring more parity to the arena. As in, the early war rides don't have that much of a speed disadvantage over the other rides that would be common.
Wotan, SirLoin might do well in it (hell, I got 5 kills in it without dying and rtbed... I don't have a problem in it either) but that doesn't mean it's not laterally unstable.
