Thats team games where resources allow fielding of multiple panthers.In low levelk games it would be end.
IS2 + SU85 are also possible in 1v1 duder. And if there's enough fuel for Jacksons + Pershing, the Axis player should have enough fuel to get out stuff to deal with that. Or they don't even need fuel because Panzershreks will annihilate any Jackson caught out of position. If they've sunk 200 fuel into a Pershing that means they haven't sunk it into Shermans and Scotts to deal with infantry blobs that are such a heavy part of the meta right now.
