I was being a bit funny, i don’t know much about technical side of things but I’ve seen people saying its about 10% better in game performance wise not sure what the truth is there.
About those planes, they all sit at their BRs because of the missiles they carry and not flight performance or things like CM count. There aren’t any planes in game with 9m/r73 or equiv below 13.0 with a good FM, and the planes that are unfortunate enough to have these things + bad BVR kit get shafted into 13.0 and power crept by current compression.
F/A 18A sits at one of the most favorable BRs in the entire game, so im not sure why it matters 7ms are identitical to 7f, you don’t want it getting better missiles and moving up to 12.7. A-10 are all at BRs where they can’t bully things with their missiles not fm or CM, F14 are the only planes with fox 3 below 13.0 sure they aren’t great, but they are still fox 3s. If you gave them 9m they immedietely shoot up to 13.0 where they are outclassed even harder and the 9m won’t make up for the BR jump and worse MM.
If you want the swiss f18 nerfed, you give it 9m, and move it to 13.0 which is a bad trade, it can’t go up because its faster and has more CM. The game is full of planes at the 12.7+ BR which have planes which are just direct upgrades of it sometimes even in the same TT at the same BR due to compression. Even below there again you have stuff like who wants to fly an f4j vs f4s, even more nitpicky or sim dependent examples like mig 23 ML et al vs MLD, or the examples in F5 family.
