I for one had no issue with various fetch quests or aether flight unlocks

I didn't care for the moogle quests. It wasn't that I didn't enjoy the story and what they were presenting-- it was that it slightly fell over the line of 'too frustrating to be enjoyed'. You can enjoy something while it still presents a challenge. For example, finding the aether currents. Finding them all was very challenging, but it was still enjoyable as it didn't cross the line from 'challenging' into 'frustrating'. I had a lot of fun with these; the compass was a neat touch. It was simple enough to be done and gave us enough context ("x yalms in y direction") to allow it to be entertaining, yet still presented us with tricky things like climbing or jumping. It was a good blend of both aspects.

While I'm happy that some people found it "easy" and "don't know what people are complaining about", I ask you to keep in mind that not all content is easy for some players. What some find a total breeze may be more difficult for other players-- this has nothing to do with 'laziness' or we want things 'for free'. I actually spent two days on and off trying to find five moogles in a specific area during early access. For me, that pushes too far into the category of frustrating rather than enjoyable. I wasn't having fun spending hours and hours flying in a circle for something I couldn't see nor had any clue to find other than a vague orange area. I would be disappointed if SE gave me a direct answer to where the moogles were hiding, but a clue within the location isn't unreasonable. Due to it being early access at the time, nobody else could help me either as the content was brand new.

Quests, exploration, and new content is supposed to be tough-- but it can still be fun.
When 'tough' becomes frustrating, it's not hard to understand where the agitation comes from.
SE needs to be careful to walk that line in balance to keep players challenged, but not irate from the difficulty.
