You obviously didn't see the calc I did. Dragonite is barely 2HKOing Skarmory with a +1 Fire Punch; not like a +2 Fire Punch will be a whole lot different. On the other hand, Salamence has a high chance to OHKO with Fire Blast. Also, you have no idea how unlikely it is to get 2 Dragon Dances without screens, even with Dragonite. If Salamence were "completely outclassed", it would be UU. Alas, it isn't.
