Hmm. I do not remember if I have posted here or not. But currently I want 2 sets of starters to get megas. Johto and Sinnoh right now. I also would like to see Moltres, Zapdos and Articuno to get Megas. And I think we will get a Lugia Mega or Primal with Lugia being the only legendary on Ash's side in the Hoopa movie who couldn't Mega evolve. It would be amazing to have a sequel to Pokemon 2000 in Sun and Moon, especially with the region most likely going to include islands, and so far, every single island chain in pokemon history, other than the Decolora Islands, has had Lugia in them. Orange Islands, Whirl Islands, Sevi Islands. All have had Lugia.
I would also like to see a hand full of Unova Megas. Namely Krokodile and Vanilluxe. Making Vanillux part Fairy.
And although Dunsparce is a pokemon that needs some love, it needs to evolve first. A Mega Dunsparce isn't going to help it at all. It would be labeled as one of the weakest Mega Evolutions and no one will use still. it needs an evolution first. Sometimes I think people forget that a Mega only adds 100 to the base stats. This would also repeat exactly what a lot of people didn't like last time. Pokemon who could have had another normal evolution, got thrown under the bus and just gave them a Mega instead.
I don't know why Audino even got a Mega to begin with. The Mega Audino would have been an amazing evolution for it.
