Solo Queue Ranked isn't meant to be climbable
Why? Because 95% of players in ranked are toxic to the point of needing to be shot in the kneecaps, myself included.
You're required to go into 5-man premades or not play ranked at all. Simple as that. Toxicity ruins games.
You could be a Master-level player and still end up in Silver because players spend more time attacking their TEAMMATES in ranked than actually playing the damn game. It doesn't matter how good you are; the game's a team game, and if your team is trying to kill itself, you automatically lose.
Riot, solo queue ranked is a mistake. Remove it.
