I hate the new ban system, but not for the reason you think
There is no decent amount of time to communicate with your team. I've never had my champion banned from me so much since this system has been put into place. I'm not complaining about yasuo being banned from me. Around 1/3 of my champ selects when I'm not trying to yasuo have been me getting my champ banned. I love this new system in theory, but I hate the way people are using it.
