I'd say that the new accounts coming in to say that sleep ban was a mistake is wrong as simply put, you had your chance before when discussions were being made before to put in your input and the community survey to vote on your decision. As Finch as said, tiering policy is not able to be tested by a suspect test because it determines balanced vs broken, and let me tell you, tiering policy is confusing. I would have to make lots of notes just to fully understand how it works, so being good at competitive battling isn't really applicable to tiering policy. I don't mind if you disagree with the decision, especially if you contributed your thoughts as you did, because people are going to disagree with any decision, but when people create accounts just to complain and diss the council or other people, that gets me annoyed. It honestly looks like they are just complaining for the sake of complaning and wouldn't actually want to put the effort in to change it, in which case, I don't think you really get to complain.
I know that your post wasn't just about this topic, but I just wanted to get something off my chest, so sorry in advance but this was kinda a good starting point.
