Reminder to use the Trust System if you want NPC dialogue before MSQ is done.

Before I start, no spoilers here, please.

So I've just finished the MSQ, and when I went back to do the dungeons to level up the trust system, I noticed that the story npcs are missing in favor of the six you have after MSQ. I thought I would be able to get back to the old dungeons and see npc commentary, especially for the first dungeon since those npcs are story only (Crystal Exarch/Guard Captain). That dialogue is gone now on this character forever, as well as other story only characters if there were any. Also zero animations on weapon skills and spells despite them having it in previous cutscenes makes me sad.

Would it be possible to have them added at the cost of no exp sometime down the line, or at least have graphics that were on skills before (or even now in the MSQ)?

I imagine, though they haven't said anything about it that I've read, that you should be able to enter with the story NPCs when you do a New Game+. Talking to the NPCs outside a dungeon has always brought up a different trust window than The Trust Window--insofar as it is specific to the dungeon you're about to enter, while The Trust Window listed only previous dungeons you had already completed.
