Gameplaywise this is definitely the step in the wrong direction (for now.). This game is already too easy and not punishing enough.
We have to ask ourself what actually is Final Fanatsy as a whole. Except some of the skills like Cure,Flare ect and the occasional references to older FF titles in MSQ and Raids there isnt much that screams "That's Final Fantasy". Bringing a staple like the Phoenix Down in a useable way back to XIV is actually not too bad.
This also gives them the option to make future 4-Man Casual content like Expertdungeons a bit more challenging.

The healer mains crying about this - please hand over Swiftcast and Surecast back to blackmage.
