>>24688621This is a stupid argument
So long as there's any kind of variation in a game, there's always going to be a "best" option. That's not the point. The point is not to destroy any chance at having a best option, but to make it so the best option isn't the only option.
If you take out landorous let's say, and everyone starts using Krookodile instead to replace it, that alone is a huge impact. Krookdile's stats aren't crazy high, he can't kill all the things that landorous could, and there's things that can OHKO him that couldn't do the same to landorous. Not to mention, since landorous isn't around lording over the meta you'd have a few options depending on your team. Maybe you want Gliscor or mamoswine over krookodile. Suddenly variation happens. The goal isn't to remove the best option, it's to make the gap between the best and second best less massive than it currently is.
Banning legendaries won't fix everything automatically. There's a handful of legends that are shit, and a handful of powerful megas that make legends look like puppies. But it would be a step in the right direction. If gamefreak finally decides to throw a bare minimum of balance at some of these busted pokemon then maybe we'd finally have a good meta.
