Hey there!
So here we have the mighty british medium tank, the Comet. Which in real life had 70-102 mm frontal armor (around 70 in the front of the chassis, and 102 on the front of the turret).
On the other hand, we have the Jagdpanzer4, which in real life had the 75mm PaK42 cannon, and used the PzGr.39/42 (a armor-piercing capped ballistic capped shell [APCBC]) which was able to penetrate a 149mm thick steel at 1000m, and 168mm at 500m.
However, in the game, the Jagdpanzer have a really hard time penetrating the frontal armor of the Comet, and doing damage. By hard time I mean 8 out of 10 shots will bounce.
I'm not even mentioning that the Comet almost never bounces from the sloped (!!!) frontal armor of a Panther, but the Panther bounces pretty nicely from the 90° frontal armor of the Comet...physics at it's finest...
In my opinion, a little bit of nerf would be handy, not too much, just make every second shot go through, and cause damage, from the Jgdpz4.
Best regards.
lets forget for a fact that the Panther bounces AP shells from the ISU-152 a known multi-role assault gun that could be used as a heavy tank destroyer and bust any medium/heavy tank the Axis had.
Or how inaccurate and unreliable the IS-2 is at penetrating Panthers armor with its 122mm gun.
or how we have special high explocive penetrating rounds for the KT gun WHILE the elefant and the Pak 43 do not.
if it was a full blown simulator you wouldnt be seeing Comets hitting your tanks but Fireflys one shotting them.
In the end if you cant beat the arcade comet you wont beat the real life Firefly.
in other words a realistic simulator wouldnt solve your problem but ADD EVEN MORE PROBLEMS to begin with.
so its best to accept the game as it is and understand theirs RNG involved in every fight that can affect the outcome of a battle.
