>>58951085>Constantly switching out mons for exp is boring tediumIt adds a layer of strategy to the base game in that you have to balance your stronger or more advantageous party members with those you want to prioritize for training. You're made to actively think about how to distribute that effort, or else you run the risk of an experientially lopsided team by the endgame. It makes the game more complex, not arbitrarily more difficult or banal.
Removing this makes the game more mindless and banal, because you don't have to engage these parts of your brain anymore. Pokemon is by no means a complicated or difficult game as far as any base campaign goes, but this was a meaningful design element which rewarded you for more thoughtful, balanced play and it's just gone now. We don't even have a choice, which is absurd.
