Hildibrand is absolutely the best and most hilarious part of the game and what I look most forward to with every patch. That said, I enjoyed the relic quest a lot as well (not so much the atma grind, been stuck on 8/12 for a week now).
The only thing that is missing is more lore. I would love for newer updates to require you to travel all around Eorzea to remote places one might miss and explain their significance. Also, trials in Dungeons like Hydra, really enjoyed that and hope for more.
