On a huge winstreak

The moment I hit promos I'm paired with people 300+ mmr under me that are plat 4/ plat 5 This is utter horseshit. I dont even want to do promos I just want my mmr back to 2.3k range so I stop playing with these horse shit players that dont have the mechanics to just CS in lanephase. working so hard then punished by riots shit system. Like god damn, let me opt out of promos, for the love of god. TF first pick 452 mmr under me plat 4. Afk until 15 minutes. Buys swift boots as first item. is this a joke riot? Least we got them toxic negative attitude players out of the system right? Rather play with 4 toxic peices of shit that make me want to go cosplay lee sin than deal with people I just had in my 3 promo's games. Like holy shit that was tilting.
