I have to disagree. Saying "Top Tier" and "High Tier" implies that "Top Tier" is better than "High Tier", for a particular conception of better. This is not, for the most part, how Smogon's tiers work. They aren't based on a conception of goodness or badness, but instead just based on usage. A Pokemon is Over-used if you would expect it to be seen in at least one in twenty battles. Once all Over-used Pokemon have been removed, a Pokemon is Under-used if you would expect it to be seen in at least one in twenty battles in the new environment that results from Over-used Pokemon being removed. Once all Over-used and Under-used Pokemon have been removed, a Pokemon is Rarely-used if you would expect to be seen in at least one in twenty battles in this new environment, and so on. In the extremely unlikely event that every player started using a Magikarp on their team, then Magikarp would become Over-used. That doesn't make Magikarp "Top Tier", as your system would describe.
I suppose you could rename the tiers as "Ban-List 1", "Frequency 1", Ban-List 2", "Frequency 2", "Ban-List 3", "Frequency 3", and so on, but OU/UU/RU/NU are, if somewhat clunky, rather traditional, and actually predate Smogon by some time. They go back to Azure Heights, which was the original competitive Pokemon community before Smogon reached the scene, and the terms thus date back to around 1998 when Pokemon Battle Simulator, the earliest PC Pokemon simulator, was released.
So essentially there is no real tier list attributing how good or bad Pokemon are but is entirely based on how much it is used. Seems strange to me.
