As we know excavations and daycare quests didnt change spawns for more than 5yrs each iirc, making the activities unappealing to the players that liked to do them in the first place.
I would recommend changing the daycare healing system to some minigame not forcing you to travel around the town to look for the medicine materials but for example brewing a mixture or making whatever medicine in the daycare building. I would also like to see refreshed spawns since they stayed the same since introducing the system to the game. (Hard to find someone trying to do the doctor quest after the bug with relogging until desired pokemon shows up was re moved)
Excavations dont really need any big rework, current system works fine but refreshing spawns would really make it more appealing. Theres opportunities to add more of the new pokemons that havent been implemented to the game and arent crucial for future planned updates…
