Vrak’s information is for that specific character, looking at the specific information on that character. There is no lie about the quest that they are on.
If they’re 60+, you don’t “suffer through” anything.
This was my experience just now on my level 65 Horde character that I created and leveled during Dragonflight:
- Picked up the quest A Chilling Summons
- Spoke to Nazgrim and clicked “I have heard this tale before.”
- Was taken to Oribos where everything was greyscale and Fatescribe Roh-Tahl gave me the quest The Threads of Fate.
- Chose The Threads of Fate and not Replay Storyline.
- Typed in “FATE,” completed the quest, was given a new one called Re-Introductions.
- Spoke with Tal-Inara in the Enclave, picked up Choosing Your Purpose and chose a Covenant.
- Noticed that Tal-Inara had the option, “I have been to Zereth Mortis” after turning in Choosing Your Purpose and clicked that.
Everything was skipped. I had Zereth Mortis and Korthia unlocked.
Edit to add that I just did this again on an Alliance alt at 67 who was created during Dragonflight with the same result.
