Playing in a full uptier is naturally very difficult. Because if it wasnt, then the vehicle would clearly be under BRed.
Su-24 and the Su-25/39 can only face F-16s or Mirages in full uptiers, and what is especially funny about that complaint is that in 10.3-11.3 or 10.7-11.7 lobbies, Redfor has the overwhelming advantage when it comes to the strength of fighters, not alot can really go toe to toe with a Mig-23MLD until 12.0.
Neither can face the EFT, but complaining about that is especially funny given that Germany is the most popular of the 3 EFT nations and is basically always on Redfor with the soviets. So im not sure what the complaint there is about. Especially as the Su-30SM2 is actually the better aircraft.
Meanwhile, im trying to play the Tornado GR1, a higher BR than the Mig-23MLD, despite being way weaker, and quite happily making it to bases and back again. Its not what you fly, but how you fly it, its easy to actually do CAS in ASB in even subsonic aircraft if you arent flying direct to target and failing to employ basic tactics like terrain masking.
