Why are Opens random pairings?

I understand all of that. Believe me, I'm not as novice as you may think. Designated pairs also is supposed to save time. How much actual time does it really save? Most of us know who we have Rd1 and also know or have heard if our opponent had left or hurt his car.
Defending it because it's how it's been done for however long is just The Emperors New Clothes mentality. They don't do it in some other divisions. The rules change often but for some reason this "house rule" is not changing. I have little interest in opens because of this rule and how it conflicts with being able to run as fast as you can without penalty
