Lottery matchmaking

This horrible meta which solely depends on how horrible my teams top or bot does really grinds my gears. It's infinitly more easy to lose a game than what it is winning (obviously, but you get my point). If I get ahead, the game is slow and hard to end. It doesnt matter how much I go for objectives, the game is always a fucking struggle, yet, when I don't hard carry and just play even with my laner, if die, I litterly lose 2 towers if I'm lucky or normally 3 towers, 1 inhib, 3 team mates, 100 LP and my moms virginity. This is fucking ridicoulus. How many games do I have to just sit and spectate when my team mates go 0/12 on a meta champion against shitty picks? The game is litterly a lottery, 50% your bot wins (theoretically, 10% in practice) and 50% (90%) chance they win. The majority of players are not playing in the botlane and get totally shat on, no wonder this game is fucking dying faster than it takes to say "Please don't fucking int for fucks sake". Horrrrrrrible.
