You know how in default when you are in a battle and knock out an opponent’s pokemon, it tells you what they’re going to put out next and asks you if you’d like to switch pokemon? That’s ‘switch’ mode, in ‘set’ mode you aren’t asked that and have to use a turn to switch pokemon if you’re at a type disadvantage, meaning they get a turn of damage or set up. Really makes you think about strategy a lot more, and is integral to challenge runs like nuzlockes.

I can’t fathom how you’d even play Diablo with a controller, just stick with it.
