a while ago gaijin removed the APDS ammo from the amx-30 DCA and the falcon, with the falcon receiving a radar in exchange, which at first seemed great but then the falcon’s radar has been broken since its addition with it failing to acquire lock from its search radar pings, I personally bug reported this issue on day one of its addition with zero response even months later,
Then there’s the other issues that these two have, the balancing changes these received in the past are still here, firstly we have the amx-30 DCA with its 40s reload still present, then also the BR placements these received in the past also remain unchanged, with the falcon and AMX-30DCA sitting at 8.3 and 8.7 Respectively, retaining their old battle ratings with these SPAAs now being used as anti aircraft, rather than anti tank, they cant really compete against the jets they can face.
as for what should change I say move the falcon to 8.0 where its needed as there’s already the marksman at 8.3, and as for the AMX-30 DCA move it to 8.0-8.3, and at the very least the falcons radar should be fixed.
