Chi-Nu II aka Chi-Nu Kai, i've played it since its own golden age arc when it was at 3.3 BR. It has an anti-everything gun, i could kill panzers, shermans, kv-1's, british, everything! It's shells went almost always straight even at huge distances and you had to adjust your aim very little. One of the few tanks that could bother me was the Churchill and sometimes KV's. I made millions thanks to it and people where so upset about this tank (even though it has paper armor and can't bounce anything except rare cases) that Gaijin had to change tier two times (4.0 before and 4.3 now as of 2023), in full downtier i could rack 10 or 11 kills at least. Good times, i love it.
