I think having Ash rotate his pokemon and catching so many in Unova compared to other regions is something that needs to continue on into other series. But they really need to get rid of this whole keeping cute /comic relief pokemon from evolving. Biggest example Oshawatt. When your using something like a Oshawatt and a Snivy in a league you can kind of predict whats gonna happen. Only time that didnt feel a problem was back when he had Bulbasaur or Squirtle cause they felt like they proved you dont need to evolve to be strong.
I prefer the pacing in BW compared to 4 years of the Sinnoh mountains. Its meant less filller but so many tournaments dragged it down. If they can make some sort of balance that makes fillers part of the main story like with TR in the background like at the start of BW or whatever Team is in play at the time.
