About the bans in ARAM

From what I understand, the bans in ARAM are going to be removed. On the one hand, I can understand why this is. In almost every game I played in or watched, almost all the bans were the same (though I don't know if that's true for the games I didn't see). I think the bans are a good idea, but I DON'T like that we have the choice.

Riot team, this is just my idea, but hear me out. The game mode is called ARAM for "All Random All Mid". We're given a random champion, up to two rerolls, a pool of rerolled champs to pick from and the ability to trade. That's more than enough control given to us for a game about chance and randomization. Why not make the BANS random as well? The champs given to us are random, so I feel like the bans should be as well. This is a mode that's more about skill than SR (I find, at least) so having to deal with bans that we don't have control over helps deliver that idea.
