It's annoying now that alot of people are going into UU, There's going to be less OU battles. I play OU, but not how people think. I really do believe that the best stratergy for playing is cross-teirs. UU pokemon do work in OU, and they take alot of people by suprise. You get the most out of everything, and I find it far more effective.
I quit UU because nobody played it, but now I suppose I should really get into it again. But It's still going to be annoying, I'm pretty sure the majority of people are going to opt for "OU" UU teams, So now instead of the usual spamming of Blissey and Garchomp, it's going to be things like Scyther and Hypno. >_>
I suppose there's really OU's of every teir, and you can't really get rid of that problem by splitting UU up into 2 teirs of OU UU and UU, because then there'll be more OU's in the second UU teir and so on. Until you have loads of teirs with only 6 pokemon or something stupid.
