Ranked Talk

I love that Riot has been making tons of Clarity changes so we can feel and see better such as the new placement system. But I have always scratched my head about this. Why don't we have a demotion series or game much like promos? Where league can let us know that we going to demote if we lose this game or X amount of games. I can tell you from experience it is super frustrating to get dropped to 0 and then your 1st lose at 0 LP and boom you're demoted meanwhile my friends can lose over 3 games at 0??? Not only would you give more insight but you would motivate players like me to play better because this next game has everything on the line. So Riot I must ask why do we not have this feature yet?
