MMR HELL

This sucks. Like, because I had a day where I had a losing streak now I got demoted. And I am in a situation where a defeat takes 25 LP from me, and wins give me 5-10 LP. I dropped from Gold 5 to Silver 1 and even winning 3 out of 4 games I still get a NEGATIVE BALANCE!

Like, I am winning more than 50% of my games, but I CANNOT climb. I will probably even get demoted again. I was at promos for Gold 4. I did not turn into an horrible player. I only had ONE big losing streak in ONE DAY.

Now I am considering quitting my account altogether and starting fresh because this is destroying me. Aside from the fact that whenever I am in promos I get ALL the AFKers that I can possibly get, I would basically have to winlike 8-9 out of ten games to actually progress. WHAT THE HELL.

Anyone else has this? what do I do? Do I just scrap the account?
