- Chi-Nu from BR 3 → BR 2 :
- Weak armor, can be easily countered by BR I-II tanks
- Its 75mm Type 3 cannon is not quite effective against BR III Sherman, Ho-I’s HEAT is arguably better at it
- Chi-To from BR 4 → BR 3 :
- Designed to counter Sherman but mostly faced Pershing at its current BR
- Now Japan has an equal tool to counter Sherman at BR 3
- Chi-Ri II from BR5 → BR 4 :
- Weak armor for its current BR
- It just Chi-To with faster reload + ineffective hull cannon at its current BR, I think it’d be fine at BR 4
