What is your opinion on the role play missions requiring you to take control of an NPC character? Do you enjoy them? Do you think they're tedious?

I personally dislike them. A lot of the solo instances in general come off as really tedious, especially in Stormblood where you're forced to either "Objective: Survive" against Zenos, or just reach a preset kill limit. The Alphinaud one is the worst offender of this, as you literally just spam press 1 for the entirety of the solo instance. You literally never have to do anything other than that.
