SPOILERS TO HEAVENSWARD AND STORMBLOOD ...obviously
(apologies for any poorly worded English ahead!)

There is something I've noticed for my humble two years of playing FF14.
Plot Armor spoils a good story.

I noticed that if Character A is tied to a quest line (job, trial unlocking process, raid) which's not tied to the MSQ progression and can be done anytime, then they are carrying the almighty plot armor of invincibility!
They may have a death scare scene and such but ultimately they will go back to their previous status and self you will see in the quest prior to whatever MSQ have thrown at them.

Example:
Yshtola is tied to the Alexander raid in HW, she doesn't die in SB
Krile is tied to the Triad Storyline, nothing happens to her in SB despite being kidnapped.
Nanamo is tied to the CUL questline, yes time bubble, events happening before 2.55 but she follows this pattern, she survives the banquet. Later tied to the GSM quests.
Lolorito, same as above.
Alisaie/Alphinaud both tied to the Coils storyline, Alisaie got a hit and blood moment in the SB teaser trailer, but she survived.
Estinien is tied to the Dragoon job quest, he lives at the end of the Nidhogg arc.
Urianger is tied to the extreme primals in ARR and start of Coils (if my memory serves me right), nothing ever happens or will happen to him. You need the NPC to unlock these fights.

And I can probably list more. But the simple fact I noticed this pattern for a while strips any urgency or concern I could have for these NPCs. I don't care what happens to them anymore cause I know they will be alright. I don't feel worried in fact I feel annoyed when I have to save or rush to their aid. Krile being one in SB. I knew she will be fine. The whole "oh she got kidnapped, I hope she is ok!" made me roll my eyes more than anything. Same for Yshtola. Now that I know of this pattern, I feel way less immersed.

Yes, I know job quests and trial quests and such follow said time bubble frame - they all have occurred before any current thing is happening but as they all have followed, nothing ever changes to them and they survive just fine to return to their self as we'll see them in said quests.

Does this bother anyone else? :/
