Losing a lot of LP per game.
I was in series to get into Silver 4, but was unsuccessful in completing my series. Oh well, it happens. But when I checked my LP afterwards I had 59 LP. That means in that last ranked game, I lost a total of 41 LP. Unless it adds both losses from series now, which I still think is a bit much. Just kinda lame to go from 100-59 right after series, makes it feel a lot harder to climb back up.
