Criteria shmiteria. "Criteria" is just a fancy official term to attempt to set something in stone to absolve any potential dispute. Just like a business owner telling you "Sorry, that's our policy, we can't budge" even though he wrote the policy and can do whatever he wants! It's silly. I think HTC's criteria is generally a good rule of thumb for adding a new aircraft, but aircraft like this would be great to have in the game. It was flown during WW2 and would likely match up fairly well with other LW birds and would be fun (The most important metric trust me). Is it more deserving than other aircraft that should be inducted sooner? Probably not from a historical perspective, but from an LW Arena Competitive/More fun perspective? Perhaps it is.
Jets never saw "combat" flying and fighting on the deck yet it happens all the time in the MA. The counter argument to that is, "It would have been possible though". Bingo! Would the F7F have been capable of entering into combat in WW2? That answer is yes, it was available, and it was a WW2 bird.
