I mean, has anyone considered the possibility that ORAS Ubers is just ... remove those elements?
Well, actually it plays a lot like XY and it's still a power level above current OU. And I'm doing testing, holding my second tournament atm, and yes it's a lot more balanced! More balanced than ORAS OU too.
My personal stance is that that metagame should be called OU, rather than banning stuff from ubers to make it.
