r77 is indeed weaker than it should and that is a large problem for Ru players in ARB.
But those nato counterparts to russian tanks r not that great, Only the swedish, the germans and the Italians get decent tanks. For the rest (France, Israeli, GB and mabye the US), they either have poor armor profile, poor firepower or terrible mobility, sometimes even two of the three, just look at the chally if anyone wants to cry about "bad T-80bvm"s. Additionally, even if Italy has a great tank in the form of the hungarian A7, they are quite lacking in backup mbts which means once they die in their A7s, the Italian players would struggle in direct combat, due to the Ariete being a hellcat without a mobility advantage, their lack of usuable spaa just adds to the issue. The case with germany is similar, the L2A6 is a much better backup to the L2A7, but its UFP is pennable by pretty much every tank APFSDS above 10.3, not to mention Germany’s lack of mobile light tanks and good spaa.
Overall, with the combination of T-80BVM and T-90M for the first-spawn tanks, the T-72B3, T-80U and T-80UE-1 as second spawn tanks, the toptier lineup of Russia is very potent and great at brawling, the combined strength of quantity and quality can best all other strong techtrees, except, perhaps Sweden. Additionally, the support vehicles such as the 2s38, 2s25m and the bset spaa Pansir makes the lineup competent in many situations. That is, not counting the overpowered KH-38ML mounted on the Su-34 which allows evapotration of entire teams and the recently buffed su-27sm acting as a fighter-bomber that has high missle capacity, the russian top-tier lineup is almost perfect.
Indeed, the lineup is not perfect, its helis lack fnf missles, its attacker is not as much a fighter as the F-16C or the F-15E or the Rafale, but it has the best overall performance which no other tech-tree has. In other words, those with equal or better mbts do not have as good avation or support vehicles, those with better avaition are worse in terms of tanks, and there are those who are worse in all regards. Therefore, buffing the russian tanks even more would just further strengthen a strong nation
