yes, in that case the t70 drives to the other side of the map, knowing there are no threats for it whatsoever and can chase off harrassers
meanwhile your pak gets swarmed by 4 cons because now the sov player knows
when it gets repositioned, he drives the t70 back in. voila wehr gets pushed off
the alpha strike of the pak should have 95% chance to hit
I mean, I can also make up a story about the MG42 suppressing the Con squads, while the Grens faust the T70 with the PaK finishing it off. Voila easy win.
Does it prove anything? No, no it doesn't.
A normal Ostheer build are 1 MG, 3-4 Grens, a pio and usually a 222 when the T70 arrives. The Soviets have 4 Conscripts, 1-2 pios and then finally the T70. Maybe they were forced into Guards or an ATG themselves to counter the 222.
If your PaK gets swarmed by 4 Conscripts, you left it undefended. That's all. As I've shown you, your PaK hits most of the time, realistically probably 3 out of 4 shots unless you set it up with a tractor or something in the line of fire. Most of the time, you hit the T70 and it has to retreat and repair. If you lose the game because of a single miss with all of main line squads having 20 range snares available, that's on you.
Which is further proven by Ostheer having decent win rates across all modes, being down in 3v3 and up in 4v4.
