If i get autofilled adc, can my opponent be too? And premades vs solo players

You already have the technology to detect what role people are playing. So why can't you also ensure that autofilled players play against autofilled players?

Or more importantly, autofilled players do not have to play against a premade duo of mains?

If my jungler is an adc main autofilled jungle and i am a jungle main autofilled adc, why did we even get autofilled in the first place? Just for the sake of getting autofilled?
