Japan 1.0 has good gun on light
Excluding the Ha-Go Japanese 37mm’s & 47mm’s aren’t bad but they aren’t anything special either since they don’t have the high pen of the American or British AP rounds or the HE post pen found on the Soviet 45mm or even the Italian 47mm
good HEAT on medium reserves
It’s less that he HEAT round on the 55mm is good and more that the 55mm APHE round is so bad that it makes the HEAT round looks good in comparison. I’m legitimately surprised by the fact that the 55 APHE round is not removed like the 37mm SA18 APHE round
It has a reserve BR arty
Except not really you still need to research them first and Japan is not the only country to have low BR Arty, Germany has the Strumpanzer II which is basically like the Ho Ro but better in every way, there’s also the Spj fm/43-44 in the Swedish TT and if Howitzers are counted in the equation the M8 Scott in the US & Chinese TT’s
It has awesome tier 2, it is so good with mobility and gun firepower (which I can see stays awesome for tier III and gets import vehicles for tier IV)
Not really. Aside from the Ch-Ha Kai, Chi-He, Chi-Ha LG, Chi-Ha SG and if we count foreign vehicles the M16 for Tier II. The Chi-To’s, Chi-Nu II and for foreign vehicles the M24 & M44. Everything else is legitimately bad; the Chi-Ri is a worse Delat Torn while being the size of a Heavy Tank, the So Ki is useless especially since the introduction of the M16, the Ho Ni’s feels like gimped Marders, the TT Chi Nu is mid at best and the Na-To does the same job as a Dicker Max but worse. The vehicles i listed that aren’t bad i wouldn’t consider amazing either just ranging from “Just Okay/Average” to “Good” with the Chi-To’s being the best of the bunch followed by the Chi-He
Japan from Tier IV onwards definitely gets a lot better though there are still some stinkers. In Tier IV specifically the Type-60 ATM and the ST-A1 & A2 are not that good at all. Tier IV Japan is better than Tier IV Israel, Italy and even Tier IV Sweden but worse than Tier IV everybody else including Tier IV France.
Nothing is worse than French lowtier
Datable. Yes France does have some horrible tanks at Tier I & II such as the AMR.34 YR so bad that you cannot research it conventionally anymore and is one of 3 tanks in the French TT that is like that. The SAu 40 is trash and i’m not a fan of the M10. Tier I (and to a lesser extent early tier II) France has the worst CAS ingame and it’s not even remotely close. The H.35, FCM 36, R.35 & H.39 is bad though they do have one redeeming factor that is they have semi-decent armour*. On the other hand low tier France do have some good tanks even domestic ones, especially their heavies. Also the Lorraine 37L, the S.35 & D2 are also surprisingly okay. France also has better SPAA than Japan has (The Ta-Se and M16 are the only SPAA that you should bother in the Japanese TT) though both Tier I Japan and Tier I France still has better SPAA than Tier I Sweden.
I’d argue that if you want to suffer playing as France play the B.R range of 8.0 - 8.7 is a better bet since most of the French Tanks in that BR don’t have stabilizers or even HEAT-FS (only regular HEAT) in a BR range that is increasingly common for Tanks to have one, the other or even both. On top of that you don’t have the benefit of facing newbies like you do in Tier I
