>>31248180Yes, I understand the definition of borderline and why these are being put there. That doesn't explain why there is any benefit to having a distinction between OU and BL, since whether a Pokémon is OU or BL has literally no impact on the banlist of any metagame.
To re-explain my problem, imagine if Smogon decided to call everything in OU with more than 10% usage "Super OU", but didn't introduce a Super OU metagame on Showdown. They just decided to call it that. Why? What possible benefit does that give?
