The simple fact of the matter is that the tank is grossly over-tiered at 5.7 in RB and completely useless unless it gets down-tiered to 4.7. It cannot pen anything above 5.0 and pretty much everything it faces at 5.3+ will one-shot it from the front.
BR needs to be based on combat effectiveness, not armor alone. Even the 4.7 Churchill is better comparatively to it’s BR.
I will go so far as to say that the real culprit is a flawed matchmaking system and not the tank itself. This is a symptom of the root cause: 1.0 BR spread does not work for all tanks, which is why you have heavy tanks clubbing everything in sight and then completely useless in the next 10 matches when uptiered.
Show me one other tank within 1.0 BR that has a 75mm or smaller cannon and does less than 99mm of penetration at 200m+. It’s packing the same firepower as 3.7 US medium tanks, which are already underwhelming at that BR. “Look how many hits I can take” isn’t a measure of combat effectiveness.
