In Air RB, 12.7 and 13.0 (especially with SARH only) are already really rough BRs. Buffs to almost every ARH missile will make it even worse.
I personally think the maximum BR should be raised to 15.0, and all aircraft with ARH missiles should be moved up one step. With the exception of all F-14s, and maybe with the exceptions of the Tornado F.3 Late, The F-5TH TCU, M-346FA, F16D Barack II (Derbys are unchanged and the Tornado flight model is horrible)
With the buffs to the R-77 base version and PL-12 which got arguably the biggest improvement, I think bumping the Su-30 premiums up two brackets instead of one is finally justified (although likely wouldn’t happen)
As someone who is currently grinding this br and only has fox ones and twos, I’m very often uptiered to fox three territory, i absolutely agree as the fox three planes are usually the prem su30s
