Play ze all powerfula AMX40 und cruassan un giving up our capitole
Much power, stronk armor
...I kid, don't do it.
Ever.
From German tree I can reсommend these friendly tanks:
Pz II. arguably one of the best machine gun tanks on the level.
Pz. I C. basically a lawn machine for anything not heavy armored.
Luchs. same as PzIC but now doesn't care if it is armored or not.
Hetzer. ROOFFLLLEEEES
Pz IV D (requires skill but arguably one of the best weapons on level IV).
Stug 3 G. Requires patience and crew but very good farmer.
Pz. IV H (like Hetzer but turret!).
VK 36.01 H. Hard armor and good weapon choices. Just don't go through DW2 branch. Don't. Do it. You don't want to. You don't.
VK 30.01 D. On par with Cromwell in my opinion and my main tank for training crews, farming and learning the game.
(IMHO) Tiger (P). The only german heavy that feels like heavy.
From Kwa:
T18 (rooffles)
M2 Medium (like T18 but turret!).
T67 > Hellcat.
(I've yet to try anything else, tbh never tried Hellcat since it's banal but oh my god they are good at random and I know why)
French: DONT TOUCH FRENCH
but if you dare, go for ELC AMX. It's total roolflz once you get the cannon.
Soviets:
I don't play Soviets since I know everything about our tanks, naturally, and more interested in parts of history I don't actually know. Can try and get to KV-2 for maximum roofles ever.
