Ah, delete wargaming in AppData and it fixed all sound problems...
The M53/55 does seem like the strongest T9 arty. I got my T92 when it was tier 8 though so I never got to try it out.
Exactly it's unachievable with the game in this current stateHow on earth do you do 4000 damage with current arty plus hoping for assists? Good thing I haven't used any orders yet.
Guess making people literally gamble was a better financial move from them than just sticking it into advent calendar.
