"There’s some handy changes coming to Pokémon Sword and Pokémon Shield to make your Pokémon adventure even smoother!
You’ll now be able to access your Pokémon Box almost anywhere, making changes to your team a breeze. "
So who cares ? teambuilding means nothing now , you have access to all of your pokemon all the time now , so there is not challenge anymore , Remember Mt Moon when u were a kid ? remember when you only had 2 pokemon left , half hp each and both with paralysis and you had no effing idea where to go and still made it out alive with the crappy helix fossil and felt the sense of pride and accomplishment ? Now you don't have to cause you can just access your pkmn anywhere like in lgpe ....
Enjoy your game.
