> Which is why I won't be buying the Let's Go series... I might as well be watching TLC reality TV shows all day for all the intellectual stimulation I'm getting out of swiping pokeballs with my finger. Wild battles were never especially intellectually stimulating anyway? Even trainer battles are only sometimes of any particular interest beyond grinding, and those are still in Let's Go completely unchanged.
There is significantly more intellectual stimulation in encountering a Pokémon, determining if it is worth capturing (good base stats, rare personality, rare moves, colors, etc), and choosing from a set of capture strategies depending on the circumstance. Maybe this Pokémon flees if attacked or frightened. That's OK, use Bind with a high-speed starter. Needs a particular status condition? Can't get their health too l…
You can't tell stats or nature with much detail until after it's caught, but you never could. Move rarity isn't a thing in wild battles in any generation as far as I know; every individual of a species has the same learnset and known-moves for wilds are determined by level. You can see the species and whether it's shiny from the overworld, without going to a battle. There's never, ever been any "only a particular ball works", though some will be more effective, but that's still in Let's Go. Fleeing is almost completely exclusive to a few legendaries, none of which appear in Let's Go. Not sure about whether Let's Go has time-of-day or swarming, but at least in principle there's no reason why it couldn't.
