Its a valid question. and you just went full katitof. Never go full katitof bro. 2 paks + high teching cost means you are not going to have enough grens + mg's to deal with the riiflemen. So your argument is just terrible.
1 p4 + 2 paks is just much much as an ass pull if say i will easily counter it with 1 sherman and 4 57 mm's
I don't know what game mode you're playing, but whenever i play wehrmacht, i queue up an at gun by 9-10 minutes, maybe i need more grens, maybe i need more pios, whatever it is. I have a pak gun by 9-10 minutes, unless you're blobbing 6 grens running them in red cover and still losing fights and you didn't bother making a med bunker, there is no way you are getting bled that hard to the point of not being able to get even one Pak40 out.
But the point of the matter is, the p4 already comes at the same time as a regular sherman(assuming map control is even) and often with pak support, why make it even earlier, and make tank rushes even quicker than they already are? USF tech tree got delayed to make sherman rushes not as viable, why reverse it for Ostheer?
