Hi everyone, I don’t speak well english but I’ll do my best to propose my ideas.
I play since less one week but I’ve globaly go impressions and gameplay experience. Graphics are beautifuls, sound render is immersive and the game is relatively stable (sometimes crashes but few). 
So here are my proposals :
Infantry : Use AT rifles and Light MG posed or proned. I think that’s will be more realistic and tactical to destroy tanks. 
Tanks : I don’t know if it’s a but or not, only on Pz III B or not, but I find the 37mm HE totaly useless, some direct hits don’t kill soldiers so it’s a little bit frustrating. 
Second thing is change shell type without shoot, as the first point it’s really frustrating to see a T60 (for example) and be killed by him cause you need to shoot and reload before being able to try destroy it.
Third thing is to remove pen indicators, I know that’s practical but it will be more realistics and tanks battle should no longer look like : Tanks spotted - green indicator - shoot - kill. And it would no longer spot tank behind bushed thanks to indicator.
Last thing is for me a little bit less important but just for the eye pleasure, original tank sights ? 
So, I hope this topic will usefull, if you have any constructive critical I’m open to everything.
Again sorry if my english is not well (you can correct me)
Have a nice day and nice game !
