Ranked leagues are messed up
The 10 placement matches really screw the league system badly. You have really bad players who get a lucky 10 that are sitting higher than good players who get an unlucky first 10. No problem, just carry yourself out right? Nope. The match making system forces match outcomes by stacking teams at every series play off. This creates a situation where silver league is a hell hole that is near impossible to climb out of. I swear to god, the players in bronze are an average higher skill level than the players in silver. I can climb through gold easier than I can silver.
What they need to do is create an "unranked" league below bronze where EVERYONE should start and work their way up. Get rid of the 10 placement matches completely.
Second, they need to fix the match making system to create fair teams. Stacking the teams, especially in a series game is just stupid. This is a team game, and more recently it has become much more "snowbally." It's not fair to expect people to "carry" a game when they have people who are severely unskilled and improperly matched on their team against superior opponents.
