Don't ban the champion I want to play
Look, I get it, you looked at my OP.GG and saw that I have 9 losses and 2 wins on Orianna, so you banned her because you didn't want me picking her.
Well guess what, I'm not bad at Orianna specifically, I'm fucking terrible at every champion, so banning Ori makes it so, so ,so ,so much worse.
Seriously, if you're going to be like that, just dodge, even if you're in your promos, at least your MMR won't drop.
edit: I was literally 2nd pick, and nobody picks Orianna these days
