The 10-champ ban system is coming but....
"So, why aren’t we implementing the esports format in solo or flex? It pretty much comes down to the needs of a team of organized players being very different from individual players placed on a matchmade team. In organized play, having some knowledge of your opponents’ strategy means you can pivot your pick and ban phases to specifically target weaker players or home in on a small champion pool."
I have no problems that it will be simultaneous, as in everyone gets to ban at the same time. I'm also okay with our bans being hidden from the enemy team until the banning phase is over. This is fine......But the main issue I'm having a hard time understanding right now is why are these bans "duplicated?" Oh my god I can see it now in my low elo games. My team including myself bans

and no team intends to pick them:
