So I noticed this while I was playing some ladder matches. I am currently a 800-900ish seraphim main and I often get matched with players with only a 100 or so or even some with negative elo. They immediately get demoralized when they see my rating and disconnect which is another problem in itself but that's not the point here. After the game ends I usually lose from 1 to 5 elo depending on their rating even though I "won" the match. The same thing happens even if they don't leave and the game is played until the end. I can't post images because my post gets too "spamy", w/e that means , but here are some replays:
9556797
9556794
These two were one after another with only a minute in between.
9557693 (This one was played until the end)
9557970
9557984
9557995
These four were also one after another.
Even so, I lost around 10 points at most so it's not that important but I thought it interesting to note.
