What do you mean. I am not sure I understand your comment
As simple as I can get:
Imagine if relic took a dump on the ability, making it absolutely horrible and overpriced like they did it with soviet SPGs vet1 ability. It would create the greatest shitstorm of our times with "omg rerik u borked axis armur needz 1000 armr buffz to cmpnsate!".
Imagine the butthurt when they would have done to it what they have done to soviet SPGs vet1 ability(double the cost, nerf efficiency by 50%, call it balanced as a ninja change).
It went through anything except a pershing like it was a paper. It 2-3 shot everything, it fired slowly, but two with rapid fire were dropping armor like sniper infantry.
