I hate losing LP when I legitimately disconnect from the game, even though we won.
Played WW jungle on my other account and got my bot and mid lane super fed, so far ahead to the point where the score was 22/7, but I ended up disconnecting from the internet at 13 minutes into the game, and the game lasted another 6. I had a power surge in my house, so it was completely unavoidable. It's funny because it shows up as a win and my winrate went up by 2%, but I lost 14 LP for it.
I don't know, it's kind of a bummer.
