Current state of tanks top tier

I love how in the current top tier meta, Russia has an absurd superiority in CAS and SAM, with any other nation you must get at least 10km away for your weapons to be effective while things like the Su-33/34 can launch a KH-38 at 20km and wipe out your entire team without much problem and with total freedom because only Russia has the only competent top tier SAM, and not to mention the survivability of tanks, because the Leopards and Abrams received their turret baskets that are spalling generators while the autoloaders and fuel tanks of the T series are spalling absorbers, and it is also not necessary to mention the problem of premium players who buy their way to the top tier of each nation and apart from not knowing how to play, they leave the game at the first death
