What Even Is Treeline Solo Q

I'm not gonna make this a text wall. Just... If I queue for solo in Treeline, I go 2/0, but my and are both 0/5...What do I do? It's not even 10 minutes into the game, and Lee leaves...Should I leave too? I mean I'm wasting my time with the rando dice. Please balance treeline. Please. I want to climb without having to use teams, and the only way that will happen is if i put 1000 games into learning a champ and literally 1v3 every game. I beat master players all the time for the simple fact of their teammates are bronze and mine arent. Like what the heck.
