@ Quaily - Ubers was created for a completely different reason than standard tier, which encompasses NU, UU, and OU. Articuno is NU because it isn't very usable/popular. Regular Deoxys, which was 43 place with 1.22% usage last January, remains Uber because in spite of it being unpopular in Uber, it is in the class of pokemon that includes Kyogre and Mewtwo. Deoxys may be moved down if we deem it acceptable for OU. But they are inherently Uber from creation, and thus only move down at our discretion. Latias is in this class of Uber at first, perhaps OU later.
Salamence was always, from the start, 100% OU, as well as Garchomp and Wobbuffet. Wobbuffet destroyed the metagame through it's abilities, and it was moved. Garchomp had the usage lead on every pokemon in OU that Scizor currently has, and was moved to Uber only with a tremendous amount of hesitation. Salamence is not anything like Garchomp yet. It is not the most used standard yet, in that it is not nearly as prevalent as Scizor. It is about as utilized as Tyranitar and Heatran, and is significanlty below Scizor. Salamence is even a Scizor counter, which means that in spite of countering the number one most used pokemon, not enough teams are able to utilize it such that it dominates the metagame.
We did not ban Garchomp lightly because Garchomp was created an OU non-legendary pokemon, which is our line for determining what Standard is. In fact, Garchomp still has many fans that do not consider the Garchomp ban justified in spite of it's overcentralizing nature because Garchomp is not a legendary pokemon that breaks the 600 net stat rule, and thus Garchomp is classified by many with the other OU pokemon. Garchomp is often legal in tournaments where all legendaries are banned (specifically, some of the Nintendo sponsored ones, such as the one that was held for pokemon battle revolution), and it is legal in the in-game battle frontier, which explicitly lists banned Ubers. It is only because the Garchomp situation led to even higher Garchomp usage than the current Scizor usage that Garchomp was banned.
If the psuedo-legends were banned to Ubers (Garchomp + Tyranitar, Salamence, Dragonite, Metagross), then we subvert the intention of Standard tier, which is not to maintain balance, but to keep Kyogre and the 680+ stat pokemon away from the battles in which we test our skills by using psuedo-legends. If you want to restrict certain pokemon, vote to expand UU to include all Standards that are not Salamence, Grachomp, Scizor, Tyranitar, and Wobbuffet, but standard tier was built for Salamences and Tyranitar users to have a place to show off. Heck, smogon loses it's function as a pokemon battle simulator completely should you ban too many Standard tier pokemon from OU; smogon is the testing grounds for the standard teams we make in game. And in game standard does include Wobbuffet and Garchomp, in addition to sSlamence, whether they are balanced or not.
