Just adding my voice to the cacophony, but i loved the Dawntrail story, tho I agree with some of the OP's criticisms (such as lack of combat/varied gameplay in general) but disagree they make DT "the worst" or the fact that they imply 6.0 and ARR are 'bad.'
My biggest criticism with the story was:
*I wanted more with Valigarmanda, he was my fave part of the story, I loved him so much. I listened to his boss music for a week straight. But the transition from him being set free to us going to fight him....he's like gone. There needed to be a cutscene or two of him rampaging across the countryside. Also, killing him off immediately just felt like wasted potential, to me. I dunno. I wanted more. (reluctant Midgardsormr 2.0? optional dialogue if you've done the four lord story line where you can have him go be with them and not be an arse instead of dying? i know xiv has never done that, just a stray thought I had typing this.)
*The final area was great (imo) if a bit slow; but from finishing the zone story to before the final Dungeon; Sphene makes zero comment on anything we did at all? Like if you cut out the entire final zone, and just teleported from the Gate in the Cenote to the door of the Final Dungeon, Sphene's motivation and dialogue virtually don't change? She made zero acknowledgment to any action we took in the final area; so to me, it felt rushed and half-implemented in regards to her writing specifically? And her "goodbye" death scene felt like it didn't really resolve anything? I dunno.
*Zorall Ja becoming the villain was whatever to me, I thought his little punk assistant was gonna have a bigger role (I legit thought he might be a sundered Ascian for a bit), and I thought him just being unceremoniously disposed of halfway through was a waste of good villain potential.
*MY BIGGEST CRITICISM was the way they handled other people's reactions towards the WoL?!?!? When you are directly referenced by the other characters, usually the Scions or ERENVILLE; they constantly refer to you as if you're some kind of bloodthirsty mongrel who's barely keeping their bloodlust in check? Or some avatar of unrelenting violence, and I'm always caught off guard by it?! MY CHARCTER IS NOT LIKE THAT WTF? I'm playing a Monk, yes I can beat you up with my fists, but the whole point is like, knowing when not to fight, and protecting others, self-enrichment/enlightenment; and Erenville casually just being like "I know how much you want to, but please don't murder these people tee hee, it might get us in trouble!" and im like....THAT IS NOT WHO MY WOL IS! And it's weird because the Scions are supposed to be these scions of Justice, protecting people to their cost of their own lives; why would they associate with like, an unfettered raging violence machine, and treat them like Besties, if that were the case? It's very bizarre to me. I hated when they did that.
Otherwise, I loved everything else, including Wuk Lamat.
