I don't think that he should be uber, because he would never be used. My friends and I have always thought there should be some tier between OU and Ubers. Pokemon like Manaphy etc would be placed here along with pokemon that are just a little too good for OU. I personally think most pokemon with 600+ stats no matter how easily countered they are should not be in the same tier as pokemon with 530 or less. That's just my 2 cents, but I do agree something should be done about Garchomp.
Ok so you are saying it is better to have a pokemon that is clearly to strong for OU in OU just because it would fail to be the dominating force it used to be?
That is a pretty crap reason to not move it up.
I do agree that there should be a tier in between OU and Ubers but I think it would require too much work to make a whole new tier from scratch.
