WTF are you talking about? You flanked the MG and achieved your goal - to move him off his position. He retreated almost immediately and was still a scrotum hair away from death. I don't see anything wrong here.
Do you think that well executed flanks should be insta-death?
It SHOULD BE, and it WAS
That's the reward of flanking. Wehr need to place their wire, mines, MG placement good enough to counter flanking or risk giving the MG42 to the US. Just one flamer / one nade / one BAR squad at the MG42 face, then it is toasted for sure
Mortar can force move a MG with one click, Sniper can force move a MG with one click
Flanking takes skill and only force move a MG? DAFUG?
