Actually, I'm more inclined to believe that the CHog was perked because you couldn't fly a sortie without seeing one (of course, this was directly related to the Hispanos!) My point is that I don't really see that many more LA7s than other planes. I see more n1k2's and spits (mostly IX's) than anything. Still see quite a few Hogs, though split between the C and D models.
LA7 has a good K/D at the moment, over 1.2 (n1k2 and spit IX also have 1.0+ K/D). LA7 has ~8000, nik2 ~14500, spit IX ~10500 kills. CHog has ~8500 and DHog has ~10000. Out of the planes I listed, the LA7 trails all in terms of kill numbers.
I'm not arguing with how good the LA7 is, I'm just saying that it's not being overused because of it's "uber" status like the CHog was.
Now if HiTech and co. come out and say "we perked the CHog directly because of the Hispanos, not because the kill numbers it had were far beyond the 2nd closest plane" then I'm in agreement. Perk the LA7, the N1K2, and possibly the Spit IX too. If this isn't the case, and it was based off of usage numbers, don't perk any new planes, and lower the perk costs on the TA152, Tempest and Arado some. Just my opinion.
