You missed the point Popeye, read my 2nd post. The F4U-1C is popular, you remove it and the guys flying the F4U-1C just jump to the next plane with percieved advantages. Maybe the N1K, maybe the P51 or even the SpitIX. In the end, it makes no difference.
Until you have a game that has a single plane you are always going to have a plane inside the game that always recieves more attention through either true or percieved advantages.
The F4U-1C has percieved advantages in the 4 cannons and the incessant squeaking regarding them. You remove all of the squeaking around the F4U-1C about 6 months ago and I'll bet dollars to donuts you wouldn't see so many.
IMO the F4U-1C sucks(as does F4U-1D) in the air superiority department unless there's swarms of them.
True air superiority weapons are the 109G2(if you get caught in a bad situation chances are you can either run, turn or climb away from whatever is pursuing you.. in my experience), La5FN(two cannons, 400 rnds, fast, turns very well and climbs well below 8K. I can get 8kill sorties in that plane), Yak9(fast, turns well, good accell, nimble. Got a 6kill sortie in that plane one time, 3 of which were 2 B17s and a Lanc) and the N1K2(no experience there.. just against it and it's really good).
You remove the F4U-1C and the only thing that will change is what plane you see in the air in masses. Nothing else.
