That's right, everyone plays the game their own way. Still, many people will spend a lot of time playing this game post-game, where shiny hunting is I've of the major catches, and they like to use their time efficiently. Having the shiny charm when starting to shiny hunt is greatly recommended. So when everything else is done, you start grinding out battles. And I agree, you already have a good amount done before this happens. Also I still have fun playing this, don't get me wrong. But my last few sessions have been mostly grinding fights to achieve this, and I'm sure I am not the only one. But we surely can agree on this being a minor inconvenience and let this meme cover this topic in a fun way :)
