Serebii/Smogon community gonna make a human shield to defend this as usual. They did with Lets go series, they gonna do again.
I mean, nothing can explain 'why' pokemon games still have shit animations move even with that big jump between 3DS and Nintendo Switch hardware. If you watch the Pokemon Sword/Shield livestream, you'll see the fire pkmn starter using the same ' don't do nothing' animation for double kick, but people keeping thinking this is 'ok',so lets sell at full price, why not?
Gamefreak will probably change the pokemon quote trademark 'Gotta Catch Em' All!' in the name of profit.
What do you mean "defend"?
It makes a lot of sense from multiple perspectives.
If there are 800+ Pokemon then it makes sense to select a few from that pool and add some new ones for each new game.
So players are encouraged to try the new ones mostly and the older favorite ones are there to complement that roster.
Since the Pokemon games take the player to different regions it kind of makes sense that some regions would not have the same Pokemon as others.
Kind of dumb to go to the new region and all of the Pokemon from all the other regions just happen to be there.
For the developers I think the issues are obvious.
On people "defending" Let's Go, here's a crazy thought, maybe people just liked it?
Whether you like it or not there are positives to not having every Pokemon ever in the game.
There are good arguments for keeping the number down.
There are negatives too but there's no real right or wrong here.
So they aren't making the game to your exact specifications. OK.
Criticize it then.
Don't think you need to sneer at people who think the decision is fine.
"Gonna make a human shield to defend this".
As if there is NO possible argument for maybe not putting every Pokemon ever in the game.
