Yuumi is a disgusting champion to have on your team and no one that plays yuumi should be allowed to pick on ranked.
i spent 36 minutes having to give up my entire jungle and map pressure because this pig of a champion building full ap with mejai refused to either ward or clear wards, at 30 mintues of game her vision score was 17, jinx with yellow trinket only had 19
i never lost a game so hard because of a map being dark/ enemy having vision everywhere this hard before in my life, and it was the first yuumi in my team in ages, i hate your champion and the people who play it.
