I haven’t played this tier in a while, nor do I have the credibility within the community to make any informed statements. That said, I’ve still been observing the Froslass situation from the sidelines. This feels like a Gen 1 UU Dragonite situation where a specific aspect of the Pokémon is more problematic than the actual Pokémon itself, but as it stands I still think the council made the correct decision. There is historical precedent for Pokémon to be banned as an unfortunate side effect of having uncompetitive Abilities (shoutouts to Gen 5 OU Sandslash by the way, bro had this happen twice), and while it’s very unfortunate, it’s nothing with an easy solution since the council isn’t the one who made these Pokémon and the game mechanics we all know and… usually love. From my perspective, if this UUBL Pokémon is/was more of a niche pick anyways, that must mean its usage wasn’t as high as OU staples, meaning that banning a Pokémon with low usage might not change the meta for the worst as much as you’d expect.
Do I wish Froslass (and Glaceon lol) wasn’t forced into a weird situation like this? Absolutely. Are there positive things that Froslass offers to the metagame? Definitely. But for the sake of tiering consistency and the fact that Snow Cloak mons are generally lower usage to begin with, I do understand the rationale behind a Snow Cloak ban.
On a somewhat unrelated note, Garchomp’s only Ability in this generation is Sand Veil, and while I think I know the answer to this, there is still a little part of me that wonders if Garchomp would be balanced in this day and age if for whatever reason it didn’t have Sand Veil. The difference, of course, is that something like Garchomp is much, much more viable than Froslass ever was regardless of evasion Abilities.
