This Helicopters can come in the range of MANPADS and AA Guns, so they are also not safe, and a laser warning system, is only a "Warning" it makes not 100% sure that the missile will not hit the target "It serves to increase the survival chances of a tank on the battlefield".
And how many Helicopters the Indian Tank Corps of ca. 3500 Tanks needs the cover the Sky 24 hours ? I dont know, what I know that this Helis are not 100% safe frome the Pakistani Anza Manpad Series and the 12.7mm AA Gun ( not inlcuded the 37mm AA Gun which have deadly range for Helicopters) !
Secondly you have to consider that the Pakistanis are producing weapons like the 12.7mm AA Gun DShK, Bakthar Shikan, AnzaI and AnzaII over a persiod of ca. 20 years if not longer, so this weapons are in have been delivered to the front line troops in masses. For the defensive part of the Pakistan Army this weapons are enough to give the Enemy a hard fight and crush the spearheads of any Indian Tank offensive.
To the Discussion that the "Bakthar Shikan is outdated", Since the wire-guided missile Bakthar Shikan is not automatic, the actual probability of a Tank-hit is under combat conditions higher !
To your useless statement:"Scenarios given by you are long gone".........I can only say Dream Scenarios like yours will only happen on the table, reality on battlefield is not a PC-game.
