I would like to say, as a person who has been playing the Japanese tree after finishing my French, I currently do not have the TKX (P). I got both of my Type 90s and then went for the Type 10. Having been playing off and on, I am still halfway to the Type 10. My 11.3 lineup now must count on praying I get placed with a team with decent SPAA because I will have reduced air defense as I must go back to the Type 93, and the only aircraft I have at my disposal is the over-tiered F-4EJ Kai (I get it has a good radar and decent missiles, but no ground ordinance and I have the Mirage F1’s which have even weaker armament and should also go down in GB rating, specially since the CT still hasn’t gotten any of its guided munitions). If the EJ Kai got its AAM-3 I could maybe see why, and also why I think the F-15J should go even farther to 11.7 at least as, unlike the F-15A it has no guided weapons and is just, like the Kai, a bomb truck that has to go against the Tor-M1/HQ17, both ADATS, FlaRakRad, the Pantsir-S1, (I’m going to leave Italy out of this because lets be real), and both ItO. If you want to use it for Air Superiority and run “CAP” you also have to contend with enemy air defenses. (I also really hope that we’re getting AI AAA to help even things out.)
TL:DR Make A2A only aircraft with lower GRB ratings and cheaper spawns.
P.S. I also think the F-16 ADF GB rating should go down, probably to 11.3 like the F-4EJ Kai.
