This is Pokemasters response the last time this was asked:
This has been answered before. The Pokedex pages and the rest of the main site is for factual content. Whereas tiers are someone's opinion. Adding them wouldn't be a big deal but Smogon's tiers change regularly so keeping up to date is a pain. You can just go to Smogon in one tab and look at the tiers, e.g. http://www.smogon.com/bw/tiers/ou then checkout each Pokemon on our Pokedex in another tab. Or check this page: http://www.smogon.com/bw/pokemon/ which lists every Pokemon with their tier. Nothing difficult about that whatsoever :)

And > Probably won't add this. > 1.Tiers are nothing official so anyone can disagree if they want. > 2.The ones that come closest to official in the competitive community are on smogon.com, so if anyone wants to know they can just go there > to see them.
