Adventurer NPCs
You’re mixing mechanics into their lore story. Having to revive them is due to NPCs being made far weaker than PCs could, so that it’s still a challenge and not just “go afk and let the NPCs solo everything” kind of deal, while simultaneously avoiding the Prophecies and Factions issue of “NPC death=failure.”
Kiel isn’t part of the personal story, so complaining that her story isn’t about them is rather moot. The later personal story is still about you, as while Trahearne’s the one pushing paperwork and ordering the troops, you’re the one who decides how to strike targets mentioned by others (who aren’t Trahearne either), and does the actual striking.
The Living Story is bound to fail, IMO, due to the whole “design allows new players to join at any point” simply because Scarlet now seems to hold a vendetta against the PC for ruining her Clockwork Chaos plans – something that won’t be the case for players starting the story now and in the future. Plus the characters beyond Rox and Braham hold little depth and are nothing more than 5 minute wonders, the story’s full of comedy despite the dark overtones, and even Rox and Braham are a comedy routine (just a better less over-done one than… everyone else but Kiel who’s as bland as watching paint dry on a tan wall).
This seems more properly placed in the Living World forum or the General Discussion forum than the lore forum, IMO.
Stop treating GW2 as a single story. Each Season and expansion should be their own story.
