Tier 6 got me laughing, but I am confused too - who plays Yuumi top? Forever alone or what?
edit: I just looked at the stat site "league of graphs" and looked at Yuumi top. It shows the number of matches for the chosen champion in the chosen role, and Yuumi top has 1500 matches in 2 days. For comparison Skarner (all roles) had 26000 matches in 2 days.
So for every 18 Skarner's you see, there's 1 Yuumi top.
