Having a random amount of bans between 5-10 every game is a terrible idea
So let's say two players on opposing teams ban a champion with a massive pickrate. One ban gets wasted from this. Then two players happen to ban another champion. A second ban is wasted.
So in total eight champions are banned, with two bans not existing. And then in the next game you play, you can very well get ten bans. Then the next you could get 6.
So. is this not a serious ranked environment? Since players can't know what the enemy is picking, they won't have any control over whether or not their ban will be stripped from them. They lose out of the potential of banning anything and have no say in it. That's funny really, because if there's anything bothering the game a lot right now it'd be lack of the player having control.
The game's already in a volatile state with how dominant certain picks are (and not any specific class of champions), so it doesn't take long to look and see the agony high ELO players face when they need to decide between fifteen champions to ban. Oh hold on a second, both teams absolutely have to ban Lulu and Ivern so I guess it's guaranteed for one team to get fucked by some top tier champion as soon as they are rendered available because they weren't banned because this game just so happened to have one less ban than was needed.
Hey, you could give every game a guaranteed seven bans and it'd be about as effective for the next 5 months and would actually prevent this maybe-you'll-hit-the-jackpot nonsense. Players would be upset that it is not ten bans, but at least it wouldn't be "haha it's actually not 10 bans most of the time guys get wrecked" like what Riot pretty much said in the reveal's comments.
Absolute madness. Gives me conniptions.
