honestly
riot has honestly just made it so unpleasant to try to climb out of bronze its not even worth it.. the players being complete garbage is one thing.. but the fact you get 1 or 2 afkers every 10 games which is almost a guaranteed loss just makes it ridiculous..so this 55% 45% chance gets reduced significantly. to get from bronze 5 to silver 5 id have to dedicate my life and it would probably still take 4-5 weeks.
edit: and to anybody that is not in bronze, i dont care what you say. you know damn well that the ranking system is horrible. if I escaped bronze or got put into something higher I would be saying theres nothing wrong too.
