well, since we now have the new brs for the f15s i have decided to make this post.
i would say the compression area begins at 11.3 up to 13.7 but other people may disagree.
the thing goes like this: play f4J/S → get uptiered and die to the f20 or f/a-18a → play the f20 or f/a-18a → die to a f-15a ->play the f15a → die to the su33 → play the su-33 → die to the premium su30s.
or well, skip all that and : play f4s/j → get uptiered and die to the su-33 or one of the 13.0 planes that have arh missiles with a plane that has a PDV HDN radar.
there is literally no point on playing aircraft that arent op broken because they get clapped by planes you cant do nothing about.
now, lets compare some planes, the 12.7 mig-29 and the 12.7 f-15, the mig29 gets 6 missiles, the ability to carry 2 r27ERs and 4 r60s, the f15 gets 4 aim7Ms and 4 9Ms.
back in the day the mig29 was fine with r60s and 27ERs since its rival the f16ADF had 4 9Ls and 2 7Ms, but now the mig29 is literally running one of the worse IR missiles of the br againt planes with irccm and sometimes ARH missiles.
and before saying “the solution is to move the mig29 down”, that is not a good solution since moving it to 12.3 would just make compression worse.
the more planes you compare in that range the more you realize how bad it actually is
