Okay, so, here's the thing.
Stopping people from banning ally picks is not going to stop them from being assholes.
Also, whenever an ally bans a teammates pick then that is your sign to dodge. Just wait until the 2 second mark when everyone has locked in their choices so you can see if someone else dodges before you have to make the choice.
People who ban ally picks are so unbelievably egocentric that there is no reasoning with them. They will do the wrong thing no matter what and blame everyone around them rather than try and correct their errors. They think everyone else is incapable and they forget the critical factor that League is a team game.
They are the special cupcakes who continuously dive 3+ enemies without any allies near them then spam question marks over the heads of their allies.
...
Then you have the players victimized by the garbage can act of having their pick banned. There are likely two things you can expect from them.
One, they are slightly tilted by it and will perform badly in game as a result despite picking something else that works and giving it a try. In this situation, you are at a disadvantage.
The other outcome is that they decide to outright troll in a petty attempt at vengeance against the asshole who banned their pick, making 3 innocent bystanders suffer in the midst of an entirely avoidable pissing contest.
