How are we supposed to finish the season with true rating with constant DC?

9/15 of my last ranked matches ive had a DC on my team leading to a loss. The season is at its final push yet the servers are SO unstable with zero loss prevention.

How are we supposed to get that last promo completed for diamond when 1/3 games people play have a DC right now. with no loss prevention. WTF is going on Riot
