Hah, reading some of these, is really interesting.
But hum. Things I want - that will probably never happen... alright, aaaah -
1. Dunsparce buff. Wether it be a Fairy typing, an evolution, or Mega Evolution, throw him a freakn' bone. He's already pretty cool - but could be so much more with just a little boost.
2. A system to make IV's, EV's, and Base Stat values viewable on pokemon in game. They're practically on the doorstep of this one, having the judge already tell you stats that are 31 IV's, Super Training now, which is the first in game way that actually shows EV's (albeit not in a numerically quantified amount, but as a bar graph and pentagraph) and loosely what a pokemon's base stats are. C'mon, just let us look at the numbers in game without pulling up a calculator in our browser already - it's not gonna hurt anything.
3. NON-LEGENDARY POKEMON, THAT HAVE TYPINGS PREVIOUSLY EXCLUSIVE TO LEGENDS. Freakn' game freak, gave SOOOOO many awesome and useful typings, to legends and legends alone; which cannot be bred, for any customization for a competitive usage. Dialga, is the only dragon / steel type. Volcanion, is the only Fire / Water. Hoopa, is the only psychic / ghost. Giratina, is the only ghost / dragon. I would love to see ALL those typings and more, on actually usable and breedable pokemon, just to have them as a non-legend.
4. Offline access to Pokemon Bank, or an alternative to the PC system that lets you store significantly more pokemon in game, and access them quickly easily and with search function. Bank is great, I'm glad they made it. But if I don't have access to wifi, all those pokemon are inaccessible to me. I get that they pack a lot onto the cartridges already, but there has to be some way to have a storage system load data in game, from an external storage location.
5. (this one's gonna combine a few) More content freedom in future titles. For one, things have hidden abilities, that we can't get access too. There's never been an event yet, forrrr, I think gen 3 (besides torchik) and gen 5 starters with hidden abilities. Some other pokemon too, have never popped up in Dream World, Grottos, or Friend Safari with their hidden ability. I'd like to see them. Secondly, there are a looooot of type combinations, pokemon hasn't done yet, in six generations now! Poison Steel, and Poison Ice would be super awesome; and Fire Grass - pleeeeease, that'd be soooo great. And now there's fairy tylpes, but there's barely any fairy type combos! Fire / Fairy, or Fairy Dark seem pretty sweet; and while we're on the topic of faireiiiiies - I get that they're new. But how the heck, do you explain only 3 standard attacks?!? ( Play rough, Dazzling Gleam, and Moonblast.) And the distribution on Dazzling Gleam; is just - just ridiculous. Things that have no business learning that move have access to it. Please, give us more fairy moves.
