I totally agree with this. I'm a huge advocate for Kyurem and its SubRoost set, but it just doesn't deserve A rank. No Pokémon that has only one niche should be A rank. Every other set bar full special Scarf set (which sucks anyway) is outclassed by Kyurem-B. I don't think people here would argue that Kyurem is a monster, and definitely should be used more, but any Pokémon that is completely outclassed outside of one set should not be A rank. Kyurem still deals with Gyro Ball, Stone Edge, Close Combat, etc. better than Kyurem-B does, though, which I think earns him a solid spot in B+.
