I need help with Obj. 780. I can’t make this tank work. I just can’t.

Does anybody here have some tricks to angle armor or whatever. I take it all.
This tank is driving me crazy. It should be easily a tank that averages above 3k for me. But i barely manage 2.4k and it feels like after every match in this thing i want to throw up or punch my screen. The amounts of fully aimed shots i miss is so high everytime i miss again i wanna jump out of my window (thankfully i doesn't fit me). It feels like some tanks have autoaim for weakspots but this is the opposite. It looks for bad angles to hit or iust the tracks or straight up miss.
Well i could go on and on with this gun especially because on paper its pretty decent. But yeah would take all day long.
And 2nd thing armor. Every T10 heavy who loads gold will pen my turret. So why not make it a med. It feels that way.
Its just like 2017 tank put in 2022 and its lost. Feels like a worse version of a Wz 5A. Has a bit of gun depression pretty high alpha and decent speed. But is worse in every aspect…
