Another cool chart I made

So I decided to update the one I made 2 months ago (here http://boards.na.leagueoflegends.com/en/c/fancreations/1tLuzoMn-a-cool-chart-i-made)

If you want me to to do this the first week of every month then at the end of the season (next season) make a graph of the downs and ups of each division and tier then vote yes.
