so I just did what the poster above said to do , I have never been to Vash on this character and I flew there from Dun on my own fly mount lvl 35, I made it easily without fatiguing, once I arrived I was given under water breathing automatically without doing a single quest, on my screen I could see many flight paths and yellow !'s, the ! on the kelp forest map that is called , aint to proud to beg begins the quest chain, it just skips the few quests when we started back in the day from SW, no Chromie , no nothing , very simple.
