The only thing going in its way is Armour Because of its Weight.
But most of the modern shells can take these out in 1 to 2 hits , this can change Depending on the Active and Passive Protection of the tank.
Pakistani Tanks will be more agile specially in dessert which can be game changer.
Unless they are up against same class.
The biggest issue i see with indian systems is you are buying machines from too many different sources which are designed to operate with their own systems it will be hard for you to share all of that data with different groups, Quickly and Securely.
And Biggest Issue front Line Indian Armour tanks will face is not Pakistan Tanks but Pakistani Light ATGM units, Pakistan has added these alot into active service recently.
Tanks are your brutes which run through enemies defence while infantry is controlling the land but if your armour starts to break down at front, it will be really bad.
