Derail some more away from the real issue being discussed.
I hope you realize that the vast majority of the people here do not agree with your opinion that M20 mines shouldn't 1-shot Pumas.
Hence, it's just turned into another discussion completely off-topic. Like this post here.
Anyways, it's not as if the USF feels the same "problem" when they lose an early-game unit like the M15A1 or the M20 (both comparable to the OKW's Puma in a strategic mindset) to a single Teller Mine. Yet I'm not seeing anyone complain about that.
