Increase Bans per Game

LoL has grown a lot, from the original 40 champs, we are now at 128 (3 times more champs) and increasing (we get a new champ, every what.. 3 months?)

And yet the numbers of ban per game have barely changed since the 4 (2 per team, now 6 ban, 3 per team). 4 champs banned out of 40 was 10% of the champ pool banned. while, now, 6 out of 128 is only 5% of the champ pool banned.

if bans adjusted with the increase of the champs, to keep a 10% ban from the champ pool, at this moment, we should be able to ban 12 champs per game (6 per team), that means at least 1 champs per Player during Draft mode (1 player gets to ban 2 champs)

Other solution would be add Perma bans at least for ranked, if not increase the numbers of ban per game, at least, keep the usual suspects out so the few ban spaces are not "wasted" on em. I mean, other kind of competitive games have Perma bans, from Card games to Video Game Pokemon

Edit: changed some math, original bans from S1 were 2 per team (4) not 3 per team (6)
