Bans increased to 5: 1 per player?

Considering the fact that there are many more champions in League right now, and more being added, it seems logical to increase the amount of bans allowed. Also, since now 3 people on each team of 5 get to ban a champ now, instead of one person doing all the banning, doesn't the next step seem to be to to allot each player 1 ban?

The potential problem with this is the increase of picking/banning phase. But I do not think this would be an incredibly bad issue.
