Tornadus is one of the most versatile pokemon in the tier. Its diverse move pool enables it to fill a wide variety of roles on a team, all of which are quite effective. Saying Tornadus is C-Rank material is pretty crazy in my opinion. I second Zaon in Piloswine getting placed in C-Tier. It's honestly one of my favorite pokemon in UU, just because it does its job so well. With out a doubt one of the best counters to bost Zapdos and Raikou (especially Sub-CM Raikou). Also is a great asset to Hail teams, being one of the only pokemon in the game immune to Hail and not weak to Fire. I honestly think Umbreon should move up to A-Tier. Its one of the best special walls and Toxic stallers in the tier, and is extremely hard to take down if you lack a strong enough physical attacker.
