The coaxial one on the Panther (which is what I thought he was talking about) only has 6 at point blank. But yeah regardless of the performance of the MG's it still doesn't justify the insane cost for the Ostheer Panther.
Let me put it simply. Something being worse than everything else cannot be justified through the lens of "asymmetrical balance".
However the Stug isn't worse than everything else. It does actually possess an above average quality.
