Did I really want the E8 to defeat the Panther? Where did I say that? I said that it does not have a “superior gun”, and that E8 needs more penetration. Even if the E8 has a penetration, like Jackson, it will not defeat the Panther. Because the Panther has more armor and health. And this is logical. After all, the E8 is a doctrinal tank, it can have a little better gun.
You want both E8 and Mechanized 76mm to be buffed/improved. But the thing is if you buff E8 it will become the USF panther for cheaper. If you buff the 76mm Sherman (IMO it will always be obsolete because of the jackson) it it outclass P4s for the same price.
IMO your question is self explainatory. 76 MM sherman is has the issue of Panzerfusilier. If you make them a call in they are OP if you make them T4 buildable they are obselete or not needed (considering Jackson). I would rahter see a
Jumbo 76mm Sherman (Comet-like tank for USF) for the Rifle Company and E8's for mechanized company.
