The matchmaking in this game is TERRIBLE

I just don't understand the matchmaking in this game AT ALL. Why, as a level 26, would I be up against a team full of diamonds and plats? In what ass backwards world does that make ANY sense? There is no reason 1 person on the enemy team should have over twice as many wins as our entire team combined. Let alone the fact that I've had several games where one teams total wins more than QUINTUPLED that of the enemy teams.

Jesus lord riot what is the reasoning behind this? It makes everyone of one team feel totally hopeless and outmatched from the very start. I like this game a lot but holy god is the matchmaking ABSOLUTELY ATROCIOUS!
