Ok lets to totally frank here, almost every uber is balanced and has counters in Ubers, if you bring a few down then honestly OU might as well bring the whole thing down, only a few Ubers such are Kyorge and Arcues might even be considered broken in the OU sense. So logically, we should go and make Ubers standard and make OU, UU. But life isn't logical, if it was we should all be eating insects for there greater protein, and killing off retarded people for there uselessness. There is a factor of opinion in the Pokemon metagame and in what people want, yes you can limit it with logical and fair bans and tiering, but there are things people just don't want to see. Honestly I don't want to play in a metagame where Dialga is your choice steel type or where Mewtwo is the feared sweeper. Yes that right there is an opinion, but thats what a large amount of the Pokemon community believes. Some might point out that I make just as much sense as the has people that want legendaries to all be banned, but the diference is I am prefectly fine playing with normally strong pokemon, but when it comes to playing with the best of the best or the best, I don't want to be playing with those giants. Its the same reason why people play UU or NU, the biggest difernce though is, a lot more people play OU as opposed to Uber. That makes OU the standard metagame, and with that its gets a few special rights. Becuase if Ubers was ever made offical, then pokemon like Blissey, which some might say in an OU staple, would become Uber by useage, but no, we are the magority and we want our good strong pokemon, we just don't want the best. Now if Ferrothorn is deemed just as powerful defensively as Giratina, then you would ban it, not the other way around, thats a basic logical principle, just becuase a Square is a Rectagle, does not mean a rectangle can be square. Ferrothorn might be on tier with an Uber, that doesn't mean Giratina is on tier with OUs.
