What I Hope Sword and Shield Does Differently

There's supposed to be a new core Pokemon game for the Switch coming out later in the year and I am excited for it. I was let down by the previous Pokemon installment, Sun and Moon, and am hoping for better things in this generation. Here's what I'm hoping Sword and Shield will do differently from its predecessor.

• Get a Dark Type Gym: The only pokemon type to not have its own gym in a game is the Dark type. We had a Kahuna in the previous generation who used Dark type pokemon, which was nice. However, if this generation reverts back to the gym leader format, please put in a Dark type gym.
• Get Rid of the Bottle Cap EV System: One of the things I hated about Sun and Moon was their EV training system. You traded bottle caps for training 'sessions', which boosted your pokemon's EVs out. Finding these bottle caps was a pain in the ass and you had to level your pokemon to level 100 in order to use this system. I hope Pokemon Sword and Shield goes back to the system used in X and Y, which was a Rocky-esque mini game used to boost the pokemon's EVs.
• More Physical Fairy Type Moves: There's only one physical Fairy type move in the entire pokemon metagame excluding the Z-move, Twinkle Tackle and Let's Snuggle Forever: Play Rough. Whether it'd be changing Draining Kiss to a physical type move or adding a new physical Fairy type move, physical Fairy pokemon like Granbull need these kind of moves to thrive.
