This does make me think - These events in particular happen in that order because the bombing is done by the Alliance PC, so it being a PvE questchain means that the Horde PC can only come in afterward because the two players can’t meet (without forcing players to queue for their PvE story questchain so that an Alliance and Horde player get matched up, then have a PvP point of failure in the middle of the questchain, and all the chaos that would entail).
I absolutely love getting to see two sides of an intertwined story, so I’d rather keep these events (where the PC canonically learns about what the other side’s PC did in their questing) than have entirely separate stories that never impact each other.
But, then I thought, why does the story not have a few NPCs who act as PvE stand-ins for the ‘adventurer’ role? Something like Nazgrim and Taylor’s squads (Wow, I keep referencing these guys everywhere), where one side’s PC works with them, and then the other side’s PC can recognize the NPCs and put some faces to the other PC’s actions even as that PC remains an interchangeable stand-in for all player options.
It’s slightly different from the existing storyline NPCs (like both PCs encountering Dreven in that chain, or Horde working with Talanji while the Alliance players later eavesdrop on her discussing her plans) in that these ‘adventurer’ NPCs are explicitly not (only) tied to the current story, but like PCs, exist over time across multiple stories and allow for longer-running rivalries and/or other emotional ties. (I’d bet that Amber Kearnen would not have gotten the reaction she did if she was in only a single expansion’s questline, even if they had made her a bigger player in that one questline. Repeat appearances and familiarity are valuable in a story like this.)
It would give a canon face (or set of faces) for each side’s PC to shake their fist at whenever one of their plans is foiled by the other factions’ operatives (aka the other faction’s PC), and therefore allow for more story interactions with each player’s actions, as there’s an NPC that can serve as a stand-in for elements that have to be left vague for the actual PC (race, motivation, personal consequences, etc).
I think there are many characters who could work for this kind of role - ideally, I’d like to have 1-3 ‘adventurers’ per playable race, who can sub in and/or team up depending on which fit the current story the best, and help represent the non-major-character aspects of their playable race. Off the top of my head, some suitable characters [or potential characters] would be:
-Alliance-
Gnomes: Kelsey Steelspark
Night elves: Thisalee Crow, [make up some new Sentinel/Huntress/PotM character to be the distant, vicious, competent WC3 archetype that people want to see in action - and as the ‘adventurer’ working with the PC, they can have more successes than most NPCs can]
Humans: [make a wandering Brotherhood of the Horse hero], [make another SI:7 ground-level agent - I’d love for this to be a young member of the Trias family who just got into the business]
Dwarves: [make a mortar team for ultimate explosive fun and great banter - like the team in Dun Morogh, but I can’t remember their names off the top of my head]
Draenei: [make a non-Broken shaman character who is one of Nobundo’s apprentices]
Worgen: Crowley, Ivar Bloodfang, Tess and/or Lorna for the non-worgen Gilnean side
Tushui: Jojo Ironbrow, Aysa sorta fits, though she may be too major for the adventurer role
Lightforged: Enaara, T’paartos!
Dark Iron: Thaelin Darkanvil
Void Elf: Umbric might be low-level enough, but otherwise it would be fun to have a spooky shadow priest or rogue to fit the archetype
Kul Tiran: Flynn is a quintessential adventurer already, Brother Pike (or make a new Tidesage character using the Kul Tiran body)
Mechagnome: [not sure about characters here - unfortunately, they’re not my cup of tea]
-Horde-
Orc: Rexxar, [make a wandering Blademaster character], [have a wolf rider who represents the average Orgrimmar citizen’s opinions]
Tauren: Aponi Brightmane, Tahu Sagewind, Jevan Grimtotem
Blood elf: Astalor Bloodsworn (either as a Blood Mage, or make a new Blood Mage character), Rommath and Halduron are a bit too high-level for this role but maaaaybe could work to get some more exposure
Forsaken: Calder Gray, Kiryn (and maybe another Deathstalker, since I can’t remember if she is one or not), Belmont would work great as a recurring rival for the Alliance even if he has a more important role
Troll: Vanira, one of the Shadow Hunter characters whose names escape me right now
Goblin: Sassy Hardwrench, the other starter zone characters
Huojin: Ji might be low-level enough and it’s fun to have him punch dinosaurs, so…
Nightbourne: Valtrois
Vulpera: Nisha
Highmountain: Lasan
Mag’har: Kaz the Shrieker
Zandalari: High Prelate Rata (or make a lower-level prelate character)
