mg42/mg34/kubel are your best bets to dealing with rifle/cons.
utilize the ostheer halftrack more, so when you push aggressively you can constantly be reinforcing. teching to t3 is actually really viable, if youre on point on not floating fuel u can get a p4 around 12-13 minute and really be aggressive with your lmg grens + halftrack + p4. vetted p4s can pretty effectively trade with t34 85s with pak support.
No, no, no. It is receipt for early and mid game. In late, katyiusha (or even 3 of them) will counter all of your inf and precision strike will fuck your PaK's and then, allies will come with 4 or more 85's with ISU/IS/SU-85 support. And where is your god now?
