So I’m on a toon in the mid-40’s, did the landing and intro quests to the Waking Shores. Sendrax offered “Adventuring in the Dragon Isles”, I accepted, went over to the scouting map, and chose Thaldraszus more or less at random – the important point being, I did not choose the Waking Shores. Got the breadcrumb quest “Thaldraszus”, completed “Adventuring in the Dragon Isles”…
…and then Sendrax popped up a yellow shielded-! for “Reporting for Duty,” which is what starts the Waking Shore storyline.
That seems odd, to have a zone’s initial quest offered without having chosen the zone from the scouting map. It’s certainly confusing, even if it’s not broken. (If it’s “always worked this way” then in the past at least the scouting map wasn’t right next to the first NPC for a possible zone choice.)
