It does - got mine!
I never got into EVs, IVs and natures, because I knew it was exactly the kind of thing that'd spoil my enjoyment of the games. All that chain breeding and everstones and curating beneficial natures - too much like hard work, not enough like good fun. It's like being an audiophile. I'm sure it's great when it works, and you have full control of everything that happens, I don't know how much day to day joy anyone can get out of being a perfectionist in that way.
At the end of the last generation and throughout the whole of this one, I've ended up a little bit seduced by EVs, IVs and natures - thanks, pokerus and Battle Subway - but I'm happy, because I never became a perfectionist and found I was more of a prettydamngoodist. I'm disappointed when the man says my pokémon are "good all round" - it's the pokémon equivalent of "You've got a really nice personality" - but I'm more than happy with anything from "above average" upwards, especially if they're "fantastic" in one of the key stats.
Deoxys, I figured, is a bit more "once in a lifetime," so after mercifully few resets, (certainly compared to my Black Tower shiny Gabite,) I got one with a top notch special attack stat, and a nature that boosted it. 26 litwicks later, I am very, very happy with my mystery gift. It's not perfect, but it's pretty damn good.
