I hope you realize that tiers are what allows variety in this game. OU wasn't created to exclude the majority of the game, because I'll think you'll find that the most exclusive metagames are the ones which use the tiers of 'weak' Pokemon.
If there were no tiers, and Pokemon was just Pokemon, every team would be Kyogre / Palkia / Dialga / Groudon / Mewtwo / Arceus because it would be impossible to use any other Pokemon without losing to a 6-uber team. But the fact is that we DO have tiers which means that if you do want to bust out your Crawdaunt or Golem, you can go play NU and not have to worry about being crushed by the inhabitants of the upper tiers.
In fact, OU is actually the 'most liberal' tier other than Ubers, because only some 20 Pokemon are banned and you are free to use whatever you wish. Sure, statistics would indicate that there is only a real variety of some 25-40 Pokemon in OU, but if you have a problem with that, there is nothing stopping you from using your Beedrill in OU, and if you don't like the quality of OU Pokemon, there's always UU and NU for ya.
And to top it all off, can you even suggest a single viable alternative to the current tier system? If you think that you can think of a better system than the one which was created and refined by hundreds of people who understand the game better than you do, I'd really love to hear it.
