Wut.
Darkrai last generation would have been rather insane for OU to handle. You can argue that it has "mediocre" stats all you want, but it had the right stats to pull off what it had to do. Dark Void nerf hurt, but then you have Z Crystals that would have significantly boosted its damage output. Even ignoring past precedent I think freeing Darkrai would have been a major step backwards for the metagame. I respect caution in wanting to suspect and prevent a witch hunt, but there are Pokemon currently that do have a significant negative impact on the metagame currently with Dynamax still in effect (Darmanitan is one I agree with a lot of people on being kinda broken), and while I think some like going for Aegislash atm is a little misguided I can certainly see why they may think it too.
Your attitude in the thread in general perplexes me. Is there something you feel that Smogon has done wrong over the years? We (Smogon) have unbanned many Pokemon and allowed them to be tested at the beginning of gens beforehand (Gen 5 we even let Darkrai free!). We try to be fair in our suspect tests and take caution on banning and keeping things around I feel. Maybe some of the community disagrees and I can respect constructive criticism, but I have yet to see anything constructive really come from your posts.
I don't know if I'm missing other posts from that user or not, but I don't see them as arguing in bad faith here.
So like this is delving into 'tiering philosophy' more than the OU metagame itself, and I realize that's more of a policy review thing and maybe not appropriate for this thread, but I do want to at least say this: people have had pretty big issues with the way we've done tiering here since like gen 4. There's always been a contingent of people who are way less willing to ban stuff than everyone else, because they're capable of tolerating things that most other people are just not okay with. I can say that as someone who played DP during the garchomp/wobbuffet days, deoxys-s suspect test, etc, and was like fine with all of those ridiculous things (I actually don't remember whether I wanted garchomp banned, 'but still'). And it's like, that's not me saying I was right about any of those being okay to keep in OU! I'm just 'wired differently' or whatever, and that's okay.
My point is that it's pretty difficult for someone wired like me to try to participate in this community. The absolute worst environment to me is one where everyone is constantly looking for things to ban or complain about or modify (it's cool if other people like that, I just do not!). So yeah,
'what will we ban immediately after we get done banning dynamax, two weeks after release' definitely trips my internal alarm too lol.
For me, there was kind of an initial phase where I tried to argue well enough in PR to change how the community worked a little, and once it became clear that that was not going to do anything, I took a step away. I'm now effectively gone from competitive pokemon apart from designing mods, since that's something I can actually control. Maybe that's like, a good thing, I don't know. But I feel like it's not great to push people out of the community who are just understandably frustrated? A lot of the users you'll see who show up to defend things from being banned, even 'ridiculous' things like Dynamax, are just trying to make the community a little less hostile to the way they look at the game.
