I know random pubs sometimes frustrates you, but I can't live without it.

Probably with my account now, I can clear most things solo, but most of the times I prefer to do it with public, I feel safer and even though there's probably minimal interaction I just feel reassured knowing there's someone else there with me.

and let's be honest that randomness is the spice of doing random pubs, sometimes you meet amazing players with top notch builds that motivates you to build more of your character/weapon.
