Considering Endwalker's obsession with body checks, and absolute failstates where if one thing is wrong then it is a wipe, even down into more casual content like Orthos/Extremes its honestly a bit pathetic they're afraid of including tools in the game that help you gauge and improve performance.

Either design the game with that in mind, or make the game about improving your own performance. Right now they're trying to have their cake and eat it too.
