5 bans and an "unban"

There's currently in League a problem stemming from the fact that 3 bans a team, tends to not be enugh to block whatever is broken in Yolo queue on current patch, as well as banning stuff you actively don't want to play against due to your favourite playstyle or champions. So what about increasing the ban amount to 5 per team, while giving both teams the option to unban a single champion. So they can force through a particular strat, or main pick they have on the team. Think it'd be particularly interesting in competitive play because it allows teams to create strats that other teams WILL have to deal with, without just banning it out.
