The Mango Rounds in the T90S Bhishma in WT feels kind of weak tbh
Ammo is based on developers’ decision, just because a tank can load and shoot a specific ammunition doesn’t mean it will be in-game. It’s the same 3BM42 for every tank with 2A46 125 mm cannon above battle rating 9.3, given that’s a T-90S at battle rating 10.7 compared to the Russian counterpart T-90A at battle rating 11.0 is certainly an advantage.
