Can we NOT have new/reworked champs in ranked immediately?
Essentially it feels like being held hostage. Your teammate hovers the new or reworked champ, and you either ban it and they int/cry/whine for 25 minutes, or you let them pick it and then they end up feeding non-stop all game while crying about how the champion "isn't good" or "they didn't get ganks." There are obvious exceptions while they do well, but I find that it's mostly a negative experience that tends to lead to frustrations from not only myself, but other teammates.
Can't we just avoid this problem and remove the new/reworked champs from ranked games for a few days, until people are actually familiar with the new champion? And even to counter that issue, why not make it so you can't ban the new champion in norms for a few days so people can test it and not feel compelled to do it in ranked? Ranked is a way to showcase your skills and to see how high you can get on the champions you understand. Not a way to test and learn the newly released or reworked champions.
