it's about what enemies you actually face, what's the MM
from 1.0 to 4.7 is low tier characterized by Shermans, T-34's, pz.IV and all the early stuff
5.0 to 7.7 is all the mid to early post-WW2 so mid tier
8.0 to 9.3's cold war is high tier
everything above that gets pulled into T-72/80/Leo 2 blackhole, with the gameplay being practically identical to top tier - so that's top tier
