F3H-2 was already too strong before the update to be 9.0, it should have been 9.3 before the update and now with the buff to the sparrows, AIM-7C hit accurancy is too great to be the first sparrow you play with and with that buff F3H-2 is more than capable to be 9.7; it has decent flight model (it is a good dogfighter), it has afterburner, quite fast in the 9.0 - 10.0 bracket, it has a really good payload for air targets.
The F3H-2 sits in a privileged position where it faces absolutely no disadvantage; none of the aircraft within a 1.0+ BR range have countermeasures (just for few like AV-8). Consequently, it operates with great freedom, as all the aircraft it encounters are not only devoid of countermeasures but are also subsonic, this renders “notching” maneuvers—which are already difficult in a slow aircraft—practically useless. The situation is even worse for bombers in the 8.0–9.0 BR bracket (Yak-28 and the B-57B—which can only equip chaff by sacrificing their payload (bombs, napalm, or rockets, in the case of the B-57B)).
I really hope they increase the BR of F3H-2 or it will be another case like the issue with premium SU-30 that they chose to ignore it.
