You have a valid point there, but I don't think the person you were replying to worded what he said correctly. How about this; every pokemon with different stats, or a different pokedex entry is considered a different pokemon. That might not be the rule since I kind of just made it up, but it would justify a lot of bans.
Tell me, do you play UU often? Do you look at every UU team you make and go "I wish I had blaze blaziken". Would you (or anyone) use him if he was BL? Do you believe that the addition of a complex ban is less detrimental than the removal of SB Blaziken from the metagame?
I play UU more often than OU. And Scarf Blaziken could help with fighting against Pokémon such as Kyurem/Chansey.
Would I be correct in saying that the fact that you answer yes to any or all of these questions would be the basis of your argument? If not, why do you advocate the unbanning of blaziken?
Because Blaze Blaziken simply doesn't have the natural Speed to be broken. It's easily revenged, or when holding a Scarf, it's walled by certain Pokémon depending on its locked move.
I know this is quite a lot of questions, but hell, if you answer at least one of them this'll make this debate way less ambiguous. I hope we can agree that clear cut perspectives make this debate a lot shorter and much easier to deal with.
