Stats of the tank as of 1.11 testing ---> https://tanks.gg/v11.../tank/gsor-1008
As you can see, it does not look all that impressive, even though it has excellent gun depression, a fully traversible turret and good camo, all stuff a tank destroyer would love.
Let's look at the ammo for a moment though.
Standard ammo - AP Mk7
As you can see, this is hardly what you would call good ammo. It's overpriced (30 credits less than the infamous 100mm shells used on T-54) and, for TD standards, penetration is abysmal.
Now, a look at the premium-special-gold ammo.
Premium ammo - APDS Kl/14
For x4 the shell price, we are getting +95mm penetration and +345 m/s shell velocity.
So now, the obvious question - why would anyone bother with base ammo on this tank, when gold ammo is so ridiculously better, and the tank being a premium lessens the post-battle credit bleeding?
