Your argument is full of bull, you don’t see how unreliable a Disruptor shot is compared to a one of the most reliable ability of the game that removes 40% of HP or more of an entire army ON TOP OF removing all spellcasters instantly from a fight just like that.
You are also ignorant that a Protoss army is massively dependant on splash damage and without it NO Protoss army beats MMM in equal suply like it’s not even close.
