The PTRS would have zero issues dealing with a T-70 because they have exactly the same range. While shreks have 5 less range than a T-70 does. Also it's easy for shreks to miss small vehicles like a T-70, while PTRS's literally cannot miss.
Also the pen on the PTRS wouldn't have issues with the T34's armor.
Your highest rank with OKW is 3859, mine is 106. I don't think it's appropriate for you to tell me I'm the one who needs to "git gud"
Your squad would get obliterated before you would be able to threaten T-70 with PTRS. That's in the vacuum. It would be even worse with infantry cover.
You need multiple shots to kill 221! Have you seen reload time on this weapon?
PTRS killing T-34? Maybe if it was immobilized for 30 seconds with main gun destroyed. You can't even kill a single PzIV with PTRs shooting constantly from behind. You have no fucking clue and talk gibberish!
In this very topic guys who are not only better than you but also have deeper knowledge of this game are telling you that this won't work but you keep repeating yourself over and over again. No army in this game have access to 2 types of infantry held AT weapons and it will stay the same for balance reason.
You still didn't provide reason why this would be justified balance wise other than "because I'd like so".
