Can't believe you are complaining about a classic Final Fantasy change that was actually needed years and years ago, regarding the Phoenix downs. It isn't to make you guys redundant or anything, there's content where it's needed like deep dungeons.
Everyone can die during one of those, not having to find a cairn to pick up a healer and having a significant stack of an item that should've been stackable from the get-go is a massive improvement over what it was. Or picking up someone during Eureka/Bozja/Occult or open world. You don't need to switch classes any more to do that.
Why is this considered such a horrible thing? Make sense, please.
