Few main quests afterwards, I will be no longer able to access The Waking Sands because
The Scions are falling back from The Waking Sands to move to a more neutral area of Revenant's Toll.
However, I didn't clear the quests originating from there to spare them for the extra jobs. This is problematic because to actually become a Machinist, I have to proceed through the main quest and get past the problematic part of the storyline. In an extreme case, I am worried about being locked out of hard and extreme primals just because of my EXP greed.
Well, can I proceed without fear? Can I still accept these quests, especially harder primals, even after that happens?
