Every dungeon should be a Variant Dungeon

[Ath192]

Same set pieces, same characters, different encounters, possibly varying level design, maybe different aesthetics, and potentially different results. Unfortunately, FFXIV isn't really built for something like a storyline with branching paths, so any different results would have to be incredibly minor (and when things are that minor in FFXIV, they're basically ditched and never acknowledged again if they can help it).
I suppose they could just drop the pretense and go full Visual Novel on us, and let people actually have a "choose your own adventure" style mini-campaign or something, but that'd probably cut into the grass development.

Slow baby pull trashpacks and an npc loitering about for half the duration of the dungeon? You can miss me with that.

Yeah, for sure, like I wouldn't suggest an NPC taking forever to move things forward or for the mob groups to be too small or easy, but the idea would be that even though defeating the dungeon always has the same result for the MSQ, the dungeons do vary from run to run.

For example, Stone Vigil, you always kill the dragon at the end however, different things and possibly bosses happen in the castle before you get to the dragon to keep things a bit more entertaining.
