-Some new ones:
-The Meloetta arc was very well written. Meloetta was the legendary that had 16 consecutive appearances in the anime, has 6 episodes of screentime (Shirona/Herself, Dawn, Onix Island, Cameron/Marlon, and Project Tempest), his finale was good, his love to Ash and the love of Oshawott was enjoyable. The only problem is that Pirouette Form didn't appear more and the Piplup part but the latter don't depend of her...
-I don't think that the series will be much better if Team Plasma debuted into the 2-partner. However, I think that Pokemon shouldn't air those weeks and start airing BW with the TP vs TR episodes.
-I like all battles in the League except Ash vs Cameron. For example, I liked Ash vs Trip although I don't like facing TRip in a 1vs1.
-I like that Ash has regressed in this League because the fans acknowledge that Ash was reset in "In the Shadow of Zekrom" and to end the aura that the fans give to Ash since the Darkrai battle. That doesn't mean at all that I like the League at all (although it isn't horrible)
-I don't like Cameron. I don't mind dumb characters but he's too dumb for me. Specially in the last battle.
-I think that Dawn should have stayed in the Project Tempest arc because Piplup was related to Meloetta. Also, I think that Dawn should made into the 1/2 of the tournaments or that she appear after the tournament.
The main thing about the Club battles aren't the battles. Is the chemistry between the characters. And that was very good.
-I don't like serious TR and the fact that they have getting few appearances recently. I miss "blasting off again", his gags, etc. Although I want them out in important battle episodes.
