Suramar Chapter Quests, need to do or?

[Bryce]

So I've unlocked the Nightfallen rep and gotten the world quests all done and shit. But all 11 chapters of Suramar quests. I know we need them for the flying achievement, but do I need to do these right away or what? Will not doing them right away impede me from doing the world quests in the zone daily or no?

I know there are some prerequisites for Access to "Court of Stars" and "The Arcway" so you'll likely want to do it just for those but other than that feel free to take your time with it.
