So.... TDs pen 100% of the time meds, so pen vet is irrelevant here.
But..... reliably penning heavies is bad.
But..... heavy tank meta is bad as well, however hard countering them is... bad... too?

Were it that simple, I'd agree with you.
But nothing exists in isolation. Were these extreme penetration values less so, you'd be able to bring down the armour values on heavy tanks without deleting them from the game.
