Daily Reminder that Promo Series need to be reworked, as they feel inherently stressful/ unrewarding

After having unsuccessfully completed my 3'rd promo series into Plat, I'm faced with the unfortunate reality that no matter how well I play, sometimes I'm matched with players who will feed every. Single. Game. After having accrued a respectable 40/21/30 KDA in the 5 games of my promotion series, winning or going even in every lane, and having respectable kill participation, I find myself discouraged, having lost yet another promo series.

Nobody enjoys promos, nobody feels that a best 3/5 solo Q game format truly displays any sort of demonstrable skill, so much as random Solo Q luck of the draw. I would really like it if the Elo system of old was brought back, in which you have an MMR rating, and the "division" you fall into is merely a range of ELO, rather than divisions which are divided up based on who gets matched with a few good/ bad teams in a row.

For demonstrative purposes, here are the stats of my last game - http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1666623883/50227939?tab=overview
