Honestly, I don't think Hail will be that terrible (but I'm fully opening myself to the possibility that at some point in the future I will have to eat crow). I just think that Hail should be giving its fair shake in the metagame, given that there are a lot of good checks to Hail still in this tier (Regice, Regirock, Klang, Lickilicky, etc). Note that I'm not saying it won't be a huge force in the metagame, because it 100% will be. It was back when it was allowed in Round 0, and while the tier has drastically shifted since then, it will still be a major force. I just don't think it will be broken as a whole. There might be Pokemon that are broken in the tier, and there very well may be Pokemon that move up a tier or two because of it (Rotom-F I'm lookin at you), but as a whole I don't think it should just be quickbanned and written off. One Pokemon I really don't buy the hype for right now is Stallrein, given that there are a few Pokemon who run Rock Blast commonly, which really puts a damper on it's effectiveness. There is also still a lack of good spinners in the tier, so Toxic Spikes can definitely limit it's ability to sit there and be fat for turns on end.
