Many people have already made posts and comments asking for him in BR3 but now I will give the final argument why he has to go to BR3
First let’s compare the armor of Chi To and Chi Nu II
Chi to has very good armor for a Japanese tank
Now look at the Chi Nu II armor, it doesn’t make sense for it to be BR4 with such weak armor.
Chi-To is still only comparable to the M10 Wolverine, but with a thin roof… but Japan has few good tanks so I understand that their armour TT is stretched.
But! Chi-Nu II is basically just a Panzer IV F2 with a slightly better gun and is not worthy for BR4 at all, the Panzer IV H which was even better than Chi-Nu II was moved to BR3 so why this tank was added for BR4 is beyond me.
They are making the same mistake they did in War Thunder - Chi-Nu 2 has BR 4.3 there, while Pz.4 F2 with practically the same cannon has 3.3. Meanwhile, Chi-Nu has worse armor and bigger size.
In our game the difference is even worse, since Chi-Nu has no coax MG to fight infantry, it having BR higher than Shermans with their stabilized 75mm cannons with armor pen 2x the thickest armor of Chi-Nu, is a joke.
For some reason the devs really like to overtier every japanese vehicle. I bet if japan got m4 sherman or t 34 76 it would be br 4-5. They literally made japanese tiger h1 br5 while german one is br 4 even tho they are the same vehicle
