go play BSS which is, I've heard before at least, the actual thing game freak balances around. Like if you're getting this heated about a decision that had most good players and many midlevel players agreeing with it, like just step away.
Gamefreak only care about VGC and BSS from a balance perspective, but also won't "fix" problems within them with bans or checks, instead letting the broken run wild until they nerf/dexit them... the next game.
BSS is included because it's one of the most popular game modes in Japan, though, which is still pokemon's main market and home and is the reason why there's still some semblance of balance in singles formats. Also the reason why things like Supreme Overlord and Last Respects exist: they mess up with 6v6 singles, but BSS is a 3v3 singles format.
As for the other guy that came out of nowhere with a high-and-mighty attitude, telling people to get logic classes and implicitly insulting the intelligence and integrity of every single person that wished Sleep gone, I don't think they deserve a reply and don't recommend engaging. Reason being, all those arguments were due
before the ban. We had discussion threads open for most of this month, around 2 weeks of open discussion. And after heated up debate spanning over 3 threads, we ended up with dozens of comments of people sick of the discussion going circles, saying it had been talked enough.
And NOW, after the fact, people appear out of nowhere to throw walls of text on why it shouldn't have been done so? No. You had your time, you chose to not participate and stay silent, you missed your chance, now you face the silence.
EDIT: actually, just realized after writing that I didn't check if they didn't participate; my apologies if I was wrong. The message stays for people that match the above conditions, though.
People that participated on the discussion complaining about the result is understandable, but this is ridiculous.
