These lines are a bit out of context, but to clarify: Im aware of shooting enemy weakspots is the name of the game. As russian vehicles tend to have consistent, small weakspots, it would increase the area where you can kill them with a new top tier round.
And I fail to see russian vehicles having problems. But to be fair, their Winrates might be influenced largely by their insane CAS / AA combination. Yes, the new round wouldnt be beneficial against the best tanks, neither the russians or the Leos. The point is american teams are falling apart for years now and action needs to be taken against it, as we can see in the last patch, when other nations were getting very good additions to their tanks, the SEPv2 war cleary not even a sidegrade.
Most of the tanks, besides the slow ones like Challenger or Merkava, are relatively equal going forward, so thats not a big advantage for the abrams, which is getting slower with the SEP1 and 2 without getting much for it besides better thermals.
I think it depends on the situation. If your facing an equally skilled player on equal terms, your armor would make the difference. Since in your Abrams, you need to aim carefully at the drivers hatch, the gun mantlet or the lower frontal plate, while on a T Series, you can aim at the very large LFP or the big turret ring/gun mantlet of the abrams. Yes, most of the times there are way more things to consider. In the game, positioning becomes very important. But when comparing tanks, you need to think of equal terms imho, to clearly see whats the better vehicle.
If thats the case, it shouldnt be a thing to give the tank its ammo thats been in use since like 20 years, right?
