I would like the TRio to change their goals and lives and not waste 1000 times on screen time trying to steal Pikachu because it makes it irritating, boring and not creative. I'd like to see James become the best pokemon keeper and Jessie become a famous TV star by interacting with her partner Meowth if that were the case.TR adds conflict or entertainment. Goh's catching adds a waste of time and throws off the pacing.
Goh is different, he will be in the anime for less than you expect. A year or two will stay and you will forget about him and then you will complain about something new in the next generation.
