Hmm, in that regard, I wouldn't have been able to buy things from Revenant's Toll until after they mentioned to me the existence of Mor Dhona in the Main Story. This is a bit after the Garuda fight, but I fought her using i100 stuff I bought there.But the point remains that because of the story it makes no sense at all to go to Ishgard. Furthermore the ishgardians wouldn't even let in outsiders, until certain events occur.
In respect to the MSQ, I agree it won't make sense going there until certain events occur. But with respect to the bigger picture, it's fine.
With the release of Heavensward expansion, such events have already occurred and Ishgard has declared it has opened its gates to *everyone* (or did they? I dunno, but I think I read this in a synopsis somewhere), this means that any adventurer passing through the Steps of Faith will be allowed entry to the holy city. It's not like the guards will halt you if you're not the Chosen One.
Imagine a role-play scenario like this (juxtaposes as actual player scenario who just bought Heavensward):
*at the steps of faith*
Newb Adventurer A: So this is the revered holy city of Ishgard. I heard they are teaching outsiders the ways of the Dark Knight there.
Newb Adventurer B: Dark Knight? That sounds awesome! Where do we sign up?
Ishguard: Halt! Who goes there!
Newb Adventurer A: Greetings, honored guardsman of Ishgard. We have come from the distant lands of Limsa Lominsa in search of learning Ishgard's secret arts of the Dark Knight.
Ishguard: You shall not pass!
Newb Adventurer B: Whaaat? But your Holy See has declared open gates to everyone?!
Ishguard: Only the Warrior of Light may pass these sacred grounds! Now move along!
Newb Adventurer B: Aw bummer
Well, yeah I'm stretching this quite a bit. But I really feel we could at least get a bit of an immediate returns when we buy Heavensward. At this pace, I don't have reason to buy the expansion until I finish the MSQ first. Is that how it's supposed to be?
