About the Unova League being horrible, I remember the ig battles of Sinnoh who I don't think that they can do it if they air now. THey can air those matches but it would be sightly less epic:
Because I know that if the DP saga was airing in 2012 and 2013, the Ash vs Paul battle will be 2 episodes and lasted around 20 minutes less (lasted 50 min), and the battle will be more simple. And we won't see battles like Zoey vs Nando and Dawn vs Zoey lasting too long. They will be , at least, partially shorter.
Thisis because in Best Wishes, the pokemon anime (and probably any action-anime) are using stock animation if there's available. In Pokemon Contests, they will respect the appeal for the most part the battle rounds... not so much.
Of course, I preferred a Ash vs Paul battle with lots of stocked animation and stocked animation in the Grand Festival to the Unova League crap.
I didn't expected a horrible league. I expect a league that was good but they won't be spectacular like the Sinnoh and Johto ones, shorter battles and with a lot of stocked animation. I thought that we can get full battles in 20 min.
