The problem with the armour is not the "best figures", it's the "worst figures". The armour has weaknesses at the top due to its sloped armour when looking at LOS. What that means is, from certain angles, a shell will go through it like tofu.
You can see it yourself. The armour to volume ratio is absolutely atrocious. Any T-90 is better than this.
Everything else on the tank has undergone continuous improvement, so, as I pointed out before, those aren't the problem. The main problem is the turret armour design is very poor and completely goes against NATO standards. Even Arjun has better armour design, even if it goes against NATO standards here as well, although that had more to do with the technological limitations of the time.
Anyway, I'm sure the Chinese are working on their own next gen MBT which will fix such mistakes.
Btw, the ZPT-98 gun used on the tank is a reverse engineered 2A46M, but has undergone its own improvements over the last 2 decades. It's nowhere near the 2A82. But its firepower is a definite improvement over our T-90S, including the use of longer rod shells. But it's most definitely not seen as much improvement as the 2A46M-4/5.
As for our needs, the DRDO NGMBT's basic design with a hull-protected crew is much better than any of the 3rd gen tanks, so we are doing fine.
