You do know the M4 Sherman base regularly bounces of the front of a Pzr 4. Most Whermact players ignore it because it's a General Purpose tank unlike the Panzer that is a dedicated tank fighter.
Panzer 4 bounces of other mediums regularly too,so its 2 way.Sherman atleast kills infantry like a scythe through wheat.Pz 4 average even at that.Right now if panzer 4 was deleted from wehr roster i don't think there will be much of a reaction from playerbase.
