You are forgetting about target size. Chance to hit = accuracy * target size. 0.2 accuracy panzerschreks would auto-hit every vehicle and would direct-hit infantry once every 5 shots.
All I want from this patch is that it puts an end to the dominance of call-in tanks and increase the viability of combined arms, especially for USF and OKW. I'm tired of facing the same commanders and spammy strategies over and over again.
Free of bugs? Well that is too bad. I made this epic mod but for some reason grenades won't always throw. I guess we can't have that in this bug-free game.
