I know the best way to stop all these "Unperk the C-Hog" threads:
Unperk the 4-Hog.
THEN we'll get some whines.

To be serious, however, I don't think unperking the C-Hog is going to change Corsair usage THAT much, especially by the dedicated Hog pilots. She hits harder, sure, but:
* The 1 and 1A are significantly faster and have vastly superior range
* The 1D's additional ordinance in large part balances out the Charlie's cannon (and if we ever get the center rack 2000lb bomb the difference will be HUGE) from a general attack standpoint (although the cannon do make a better choice for deacking and busting light GVs).
* All three of the other 1-series Hogs are more maneuverable. The difference is subtle, but there. And enough that the top Hog pilots know the Charlie is in trouble in a protracted maneuvering fight against any of the other Hogs.
* The Brownings don't have the punch of the cannon, but are more than serviceable against any air target in the game.
* The F4U-4. I shouldn't need to even EXPLAIN this point.
