This. I can deal with the other changes, the nerfs of certain items, the nerfing of useful farming moves or abilities, the destruction of berry farming, but to require the lead Pokémon to no longer be fainted to gain an overworld effect is just an arbitrary two fingers up from the devs, IMO.
I’ve used a lead fainted Pokémon with some ability or another since pretty much day one (or at least since I returned to the game earlier this year) so that I may farm for decent IV efficiently for breeders, or any other number of reasons. Now I can no longer do two things at once, farming/grinding and watching a film or reading an article or journal, as I will have to constantly shift my focus back to changing Pokémon once I enter a battle to my catcher or my fighter instead of being able to enjoyably and efficiently complete my actions with one eye on the screen and the other on what I’m doing in the real world.
Since I returned to the game earlier this year I’ve clocked up nearly 500 hours play time, doing roughly 80-100 hours a week due in no small part to being on long term sick leave and not being able to do much else, but for the first time since I returned I’ve lost all motivation to play because of this, and to a lesser extent the other, changes.
NB: I’m well aware no one actually cares for the story of another person but I just wanted to get my two cents out there whilst I had the motivation to do so.
