Just did the event, and I actually enjoyed it. Nice little story, and I love the glam seeing it up close (The ARR symbol is real neat). Perhaps my fav Moonfire in a long while. Just wish that like others say, it was longer.
My preferred take would be to do seasonal events like mini-tribal quests. Have a new part of the story unlock each day, in this case we could have a new ‘event’ we had to help our new friend with each time before the final. Not that I think SE will ever do that, for better or for worse they seem to want and stick with a ‘one and done’ strategy. I appreciate how it means less FOMO then other MMOs, but still a shame.
I agree that it would have given us more to do, but part of me dislikes FATEs in seasonal event quests, mostly because I would love it if old ones become repeatable one day and FATEs make that hard to do. Plus I wish they would actually put worthy rewards for us to far outside of just party poppers.
