In my opinion, the aircraft doesn’t perform particularly well on the BR.
I found the following about the aircraft:
“The available upgrade kits made the F-4 a versatile fighter / fighter-bomber. R2 included a 300-liter auxiliary fuel tank, R6 the ETC 500 (ETC = electrically operated carrier for cylindrical external loads, 500 kg) bomb layout for one 250-kg bomb or four 50-kg bombs. The 240 F-4/R1s produced included mounting points and cable connections for the installation of underwing weapon pods.”
So please Gaijin / Darkflow: give it either 4x50kg bombs or a single 250kg bomb to fullfill it’s role as fighter-bomber
