I think perk points is a somewhat dynamic arrangement to try to balance arena. In that sense, I don't mind which planes are perked at any given time. I found the cheap perk solution quite sensible, in order to cure the C-Hog disease, or any other arising in the future. It is utmost boring when you see a genetic-clean horde of C-Hog coming low from any CV. Not a single TBM's to make mud job, let alone Hellkitties..Zekes? you crazy?.
Plus, C-Hog encourage the no-brainer, fly-straight, Quake-minded style of playing. That's the main difference with N1K2. Not that N1K2 can be another cheap perk (maybe, maybe not), but just stating the difference in flying styles. Yes, C-Hogs are (roughly talking) easy preys. That's because you see more and more people T&B'ing with this bird against Zekes, Spitfires, N1K2.... Does it make any sense?. Only if yo think on newbies or Quakers giving all for a snapshot or a HO. Sad. I like this game because of its balance. You can tell whatever, but now (at least in terms of Arena appearance) it is NOT. Way too many F4U-1C. Of course, it's my opinion. I bet somebody out there thinks Quakebirds are still too low in numbers, and FW190-A8, Zeke, 109's, C205, C202 should be perked, better if banned.
Flame on,
