Gimmicks/mechanics you'd like or don't want in SWSH, either in or out of battle.

I'd personally enjoy a farming option sort of like a passive secret base/day care with customization and upgrading options. You can put six mons in at max, with different equipment/furniture that lets you train specific stats or exp. Maybe IV/EV instead but I don't know if that'd be broken potentially. They can farm items, sometimes rarer ones like stones, passively. Maybe it'd also allow you to enter Amie but with an interactive environment, since I don't know if that's coming back. You can put trade requests and check out other people's farms as a new option under wifi trading.

Also hoping for an egg incubator item.
