How long time planes br 9.0 or 11.3 will fight against 10.3 and 12.7! espescially against f14 with free fakour!
Uptiers/Downtiers are only +/-1.0BR. Fakours are only on one airframe (F-14A IRIAF) which is at 13.0, the maximum downtier it can see is 12.0
A squad with a max BR of 9.0 cannot see 10.3
A squad with a max BR of 11.3 cannot see 12.7
Another note: you are an arcade player, BR is a bit different there but the rule of +/-1 still applies
You have 55k+ games and don`t know you only face +/- 1 BR?
Give us pictures of you facing a 10.3 in a 9.0 or it didnt happen
Notably,

So thanks to this, a 2.3 lineup can see a 3.7 plane because the 3.7 plane lineup is matchmade with 3.3 BR.
They could be playing arcade, which downtiers a plane by 0.3 if it’s the only plane in the lineup.
Ah, i blissfully ignore arcade so aint got a clue
I’d like to note, I think arcade’s BR system calculations are convoluted and just kinda bad overall, hence why I dont play the mode.
With this information in mind their point makes more sense, however such atrocious BR can be fixed through just having the highest BR’ed vehicle calculate it
yeah in arcade, but ther br can’t be more 12.3 when i choose planes with maximum br 11.3
