I am very hype for Legends and I have a few big wishes for the game that I hope come true.
Follower Pokémon - Self-explanatory.
Pokéball crafting - I think it would be cool if the main way that you obtained pokéballs at first was by crafting them yourself. Maybe you could adapt different elements into the balls to create different variations.
Riding Pokémon - I think an open-world game would be a great place to bring a ride feature back into the game, especially for flying Pokémon! Since the dodge roll has been speculated to be used to help avoid Pokémon attacking you, maybe you can do a charge attack while riding on a Pokémon's back to enter a battle or avoid it too?
Camp/Refresh - I personally have wanted the Pokémon Refresh features back since they were missing in Sw/Sh, but I think they would work well in Legends along with the camping and cooking from Sw/Sh. I can just imagine setting up camp in a dark deserted cave, feeding my team a bowl of curry after a hard-fought battle or something.
Settlement Building - I think this is the least likely to happen, but I think that a settlement building aspect that allowed you to help build up other towns throughout the region would be great.
Side quests - I'm hoping we get some form of side quests that allow us to help flesh things out around town. For example, you could get a side quest to help the PokéMart owner beginning to sell specialty balls by crafting a few balls for them and then giving them the recipe.
Gym creation - A big hope of mine would be that there is some sort of story arc that leads to gyms being created throughout Sinnoh, and you have the ability to be a gym leader yourself. I know this game is set years before Pokémon Training became a thing, but maybe this could be the era that it all came about in Sinnoh? Again, that would be a huge leap, but cool nonetheless.
