TL;DR:
Tanks are balanced by tier because balance by history isn't balanced.
Which is exactly why the Tiger is tier 6/7 (depending on model) and the T-34/76 and T-34/57 are tier 5.
Or if you want to compare it in Wart Hunder, since it has a slightly different approach to tiers and MM:
Rasha:
T-34, T-34 (1942) and T-34 Ekranami are all battle tier 2.
T-34/57, T-34-85 (D-5T) are battle tier 3 (BR 4.0 and BR 5.3).
T-34-85 (ZIS-S-53) is battle tier 4 (BR 5.7).
Germany:
Tiger H1, Tiger E are battle tier 3 (BR 5.7).
Tiger II (Porsche), Tiger II (Henschel) are battle tier 4 (BR 6.3 and BR 6.7).
Tiger II (10.5cm KwK) is battle tier 5.

All in all, I think this boils down to core design problems in WoT. For example, all tanks being balanced towards being damage dealers rather than some being pure spotters. Or, all tanks having enough view range to spot for themselves rather than having to depend on dedicated recon tanks. Or, almost all maps favouring close quarters brawls rather than focusing on strategic positioning, concealment, sniping etc.
Because tanks simply aren't fast, and some tanks are really slow.
Even on El Halluf it takes a churchill 7 a full 2 minutes to reach heavy corner.
Now imagine if the map was 4 times bigger (2×2km instead of 1×1km); you'll never reach the action in time to give a meaningful contribution.
You'll either arive too late to do anything with the rest of your team having moved on already meaning you do zero damage.
Or you arive too late to support your team leaving you overwhelmed by the enemy and die with barely any damage done.
And of course the game is balanced towards dealing damage since that is what kills the enemy, and what is being rewarded the most.
One could argue that spotting needs to be rewarded more, but I don't exactly notice most LTs being great spotters.
