The " why " is written all over their rants as they leave, whether it’s true or not, that’s their perception of the game or the game mechanics.
Like this last example, this is why:
That’s one.
That’s two.
That’s three.
Again, whether it’s true or not, whether they know how to counter it or not, that’s their perception of the game.
That’s ‘why’.
Not saying I agree, just saying it’s the general ‘why’ as I read it
