Yea, you don't get to talk about anyone's rank since you're level 13 and have 0 games on op.gg. If you want to contest that, i suggest you hop on your real account and have a discussion with your rank right where your mouth is, TempName54846. Or maybe you're banned so you're chilling here.
Secondly, this "optimal performance" you're speaking of is only applicable to top tier Challengers and pro players. You don't need to concern yourself with what's viable unter the optimal circumstances, considering you'll never even smell that rank, let alone be there at one point in time. Don't think of this as an insult, i won't be there either. As a matter of fact, 99% of the playerbase won't.
If you want to make a specific case that pros and high Challengers need more bans, be my guest. But the topic of this discussion is that someone requested that we need more bans because, oh lawdy, they just can't deal with champions in general. And what better way to win a lane then to eliminate the opponent entirely from picking anything viable? It's all shite picks for them, you get the good stuff. Because that's fair.
