If most of your matches look like that screenshot then the problem is you. I'll ignore the time on the crystal due to you being ranged, but only 1 kill and 1 assist is really really bad. The matchmaking isn't great and I have my share of bad matches, but you gotta be getting 5-10 kills (and just as many assists) if you wanna climb, ESPECIALLY if you're rocking MCH. Even if your team is struggling, MCH can get free kills pretty easily if played right and can turn a match around just from getting the right kill. Only getting 1-3 kills a game or having a low assist count isn't acceptable unless you steamrolled them.
