This matchmaking is a joke in all gamemodes

Be it SoloQ, Flex, Treeline or Blind Pick, enemy team always has double or triple my team's score. It begun middle of last season and has made it to new season as well. I can't even enjoy blind pick games (I keep away from ranked cuz it's completely unplayable, im not joking) without enemy completely pubstomping mine, it's like im up against full premades every game who 4 man gank bot or toplane and take turret on 7th minute, sweating their balls off and making my life miserable. I swear i haven't won a single game when i solo queue for blind pick for over like a month. When i premade with friends its alright, we win, we lose but my whole match history is red when i have been trying to have some fun by myself. Feels like it will never change...[zombie-brand-facepalm]
