You ever think that League matchmaking has turned sadistic and is punishing you?

Every so often I'll have a stretch where the majority of my teams make me question why I even play this game. I'm on one of those stretches now.

Last match, against a team looking for picks (Annie, Sona, Udyr, Fizz, Lucian), our entire map was dark, whereas they seemed to always know where we were. Makes sense when they warded 63 times to our 43, 13 of those wards coming from me, my blue trinket wards each lasting about a second thanks to them living in our jungle. On top of that, our Nautilus was running Thunderlords and going full AP (in his first match with the guy) and our Amumu was doing the same, going Runic Echoes, leaving us with no real tank.

Yesterday, I had a match where our team got only one kill, thanks to me. The match ended 1 v 21. Plus our 0/5 Lucian, who had nearly 1/4th the damage (1,212) of his 0/4 Annie support (4,954), was raging in chat the whole time, telling Annie just to go elsewhere on the map because she doesn't know how to lane.

I know I've just hit a patch of bad luck, and that I've still managed to have some quality matches during it (22/2/8 hard carry as Nautilus yesterday), but... just... I've been trying to practice for ranked and most of my matches are too lopsided to learn much from, as well as too mentally and emotionally taxing for me to even feel up to playing ranked afterwards. Last night I told myself I was going to play ranked no matter what... and then 2/3 matches went to complete crap (on top of other things that wound up weighing on my mind last night).

Anyway... I assume I'm not alone in having these sorts of stretches from time to time, as they're bound to happen to all of us at some point. What's your worst stretch?
