I’m having SU-152 and enjoying its stock gun so far, and ISU 152 seems promising enough with its 152mm still somewhat doable before getting BL-9.
But really, Obj 704 with that thing as stock gun and 60k exp away from actual gun? Against tier 9 and 10?
How do you even grind this thing if not firing golds. It feels like the old day where IS-4 would technically be a nightmarish grind with stock 122mm cannon.
