TL;DR: Add Chi-Ha Kai as a foldered vehicle for Ka-Mi and lower its BR from 2 to 1.
Long version:
Yes, I know that it was an event vehicle back in 2023, and I hope that those who got it back then won’t mind this suggestion, especially since we already got some previously event-unique stuff in tech tree.
My suggestion is in the title, along with an extra one to lower its battle rating to 1. Why? Because Japan, unlike other 3 nations, at this point in time doesn’t have a BR1 tank with a potent main gun that can deal with downtiered vehicles reliably (compare them to Soviet 45mm, German 50mm or American 37mm), with its only options being 37mm guns that lack penetration, any kind of HEs (I am not even asking for good ones lol), as well as any decent machine guns. Chi-Ha Kai can cover the need for a decent tank gun with some (terrible, but better than none at all) HEs on top of it, while for good HEs you can just choose to use a higher BR vehicle instead.
I’d like to have Ka-Mi be foldered under Ha-Go instead, with Chi-Ha taking its place, but so far there were no tech tree rearrangements, so that’s why I am asking to have it at least be foldered.
Plus, we need some kind of mass-produced Chi-Ha as a tech tree vehicle and not just a Short Gun version, it’s like if Soviets would have their T-34s or Americans their Shermans exclusively as event and premium vehicles.
