Honestly i love the way the 10 ban was done.
Its great in a both ways that it doesnt make the champ select longer (it makes it shorter actually!) and it gives every player a ban WHILE at the same time handling well the whole "but X Y Z meta champs will have a 100% ban rate!" with the repeated bans which will often happen to fotm champs (so every player gets a say on the ban but the effective bans will probably be like 8 per game), so otps arent as screwed, also rewards you for banning more specific champs that might counter you or your team rather than one whos just "op" atm.
