Anyone who has played early jets recently knows the current unbalance of the 7.x lobbies. The F2H and Su-11 dominate due to their flight performance while everyone else suffers. The F2H alone outperforms every 7.3 that isn’t the Su-11 due to its combination of acceleration and good handling that make it very easy to fly.
Meanwhile, the F9F-2 is 8.0 BR for very similar flight performance to the F2H and 160 more rounds of ammo. It turns a lot worse than the F2H so why the .7 BR increase?
If the Su-11, F2H and F9F were all 7.7 BR, many balance issues would be alleviated. It is currently possible for the Ki-84 hei to fight a carrier aviation jet fighter which cruises at speeds twice as fast and carries nose-mounted ANM3. This is ridiculous.
