Just played it today and it was tragic at 6.3/7 , only one good game where I uptiered it to 7.7 and it went fine, but I know it can do better if corrected in-game
The ZSL 92 was an IFV and thus should be reclassified to the light tank class, and scouting should also be added. Why is the BMP2 MD or Marders classed as light tanks but the ZSL as SPAA? I know there is a gap in the anti air sector for China, but SPAA should be reserved actual purpose built SPAAs like the WZ554 (WZ554)
After re-classing it as a light tank, the ZSL should receive its APDS/APFSDS belts, improving its anti tank abilities.
After all the mentioned changes, the vehicle could get uptiered to 7.3 as an analogue to the BTR-80.
