While I appreciate the answer, I’d much rather some world building be established through dialogue for hints of things we’ll see in the future.
Using Gilneas as an example, although this applies to many locations and groups.
We don’t need Gilneas added as a playable city right away, but the state of the city has constantly fluctuated for a decade, sometimes it’s occupied by Horde and other times it’s abandoned and sometimes it’s just a blighted hole in the ground.
I don’t want the time skip to hold off on the state of the city for the sake of the player being present. It could be mentioned the land was reclaimed, the 9.2.5 diplomacy mentioned by Calia paid off and the city is in a current state of reconstruction.
Things like this can co-exist with players being introduced to the area in a compelling quest chain that compares to 9.2.5’s Undercity quest chain.
I’d rather know the city was in the process of rebuilding than just ignored, because it gives me hope that eventually we’ll return to the zone and it’ll be a bustling city. It gives me perfectly justifiable in-universe headcanon that my character worked on the reconstruction during the 3 years off.
If we’re holding off for a 9.2.5-esque quest chain compared to the Undercity, we’d still be leaving the city in a state of disrepair and unusable by the end. I don’t think many people want that? Ultimately, I’d argue people would want the final result more.
Not suggestions but just throwing it out there that rebuild can still occur and you can still make a compelling chain out of it. Perhaps Genn handled logistics in Stormwind the entire time, and he invites us to see Gilneas on his first visit since the Catalysm and initial reconstruction.
Perhaps we visit the city with the refugees that formed Bradensbrook or Surwich, and it’s as much an introduction to the city for them as it is for the player.
Things like that, rather than players left idle and the world feeling like it paused while Night Elf and Worgen refugees lived in squalor on Stormwind streets.
