Realtalk though I don't play Pokémon nearly enough or even at all competitively to know what the hell I'm doing.
I just play them for the story?... or did at any rate. But yeah when I heard about Shinies first way back when Gold/Silver/Crystal came out I was like "pff yeah just like mew being under the truck hahaha" and then it turned out to be true and "WAIT WHAT!?"... the shiny thing at any rate.
@Nine Well, the idea was that by exerting their, say, special attack, a pokemon would become better at using special attacks.
I don't know why the EV system is based on the pokemon you defeat, though, rather than what you actually do in the fight.
@Rosemary see the stat exp thing makes total sense! EVs and IVs just... don't. they're random, arbitrary, and make no thematic sense either and i hate htem so much
@Nine stat exp worked the same way as EVs, I think.
IVs are just meant to make each pokemon unique, so that not every freshly-hatched bulbasaur will have identical stats.
@Rosemary Ahhh yeah that's the thing! Thanks. I'd forgotten about that bit ^^ But yeah again what the heck gamefreak
