the game is not a vacuum, the vid shows what happens to inf in the open. Of course behind green cover with the panther sitting there things will be different but lets be honest this will never happen.
Lategame you will catch a rifle squad sidecapping a VP, Panther (like the comet) does a pretty good job at killing these squads with the MG's similar to the comet.
no buffs needed, it's already cheaper with better vet.
Late game is full of yellow cover ( beacuse Arty) and sand bag are a thing (and demo 360 no scope green cover)
Btw
MR. smith i see you looking in this post , could you please look for the video you posted on the old panther vs comet post ?
