You seem to forget that a) panther is essentially a heavy vehicle and b) unlike the Faust at nodes don't engine dmg heavies 99% of the time ... Meaning it is by no means guaranteed to engine DMG a suicidal panther
People who cannot kill a freaking blitz panther should play the campaign from the beginning, or even the tutorial.
Just some cons and a single SU85 can kill off the suicidial rushing catz, not even mentioned the lol noob friendly AT nade would not microed away like sticky.
