Top tier is currently is screwed in general, it’s the epitome of about 15 different issues with different ingame features (some implemented for good reasons but never updated and some straight up mismodelled).
Russian (and Chinese) CAS currently seems to benefit from them heavily since they use HE munitions rather HEAT which are much more reliable at killing tanks (since IR guidance on anti-tank munitions is modelled horribly, meaning that munitions which can overpressure are much better, and HEAT overpressures worse than regular HE). Russian top tier tanks themselves are far from being broken when strv122’s and leo2a7’s exist, since they’re slow, have mediocre reloads at best and aren’t too difficult to kill.
Gaijin has to fix a ton of issues to fix top tier, to list a few: aa spam/aa missile spam, cas missile spam, IR guidance on anti-tank munitions, revising overpressure, decompression to 13.0, complete heli balancing and research rework (helis for the most part are either dogwater or quite overpowered with few ones in between, also heli research jumps from ~160k rp to ~360k rp after the second heli in the techtree)
