MSQ
A nice addendum to Eulmore and good to know that the sin eater victims can possibly be saved. I am glad about having the pseudo-confirmation that Ardbert rejoined with us as well (am sort of confused why they weren't able to say the same thing about G'raha when he comes from a time after an 8th rejoining but eh).
It was nice to play out the events after the ShB cliffhanger, though who the new white-robed figure actually is and how they plan to get Zenos into contact with Zodiark is anyone's guess. The Ardbert look-a-like is probs one of the 'warriors of light' Elidibus was talking about... but I feel like they are just gonna be "lesser Ardbert" if they don't throw some curveballs.
Alliance Raid
I dont have much to say on the story so far, and will keep on musing until more concrete information becomes available in 5.3/5.5. However, I WILL say that the "collection" feature and (more specifically) the ability to revisit a version of the instanced raid area after the duty has been completed to gather more lore is something I actually love and have previously wanted for other instanced duty areas like dungeons and raids. I realise the dev team probably can't do that for every piece of group content, but it is gratifying to see at least ONE thing having such a feature, and hope they continue it with the rest of the raid series.
Pixies
So the pixies can make/influence dreams.... that's a somewhat chilling thought. An Lad really gives of the vibe of being reincarnated Lightwarden Titania, especially since they seem to react negatively to us. Maybe after being doused in light for so long, after being freed, they just thought it was too dark. Nonserious speculation, but we'll we see how it plays out over the next few weeks.
