I gotta tell you, Elbaf has been a very boring arc.The great giant civilization of the world being just a few scraggly viking huts. Where the most entertaining part of the arc was lore about stuff characters did 50 years ago that is irrelevant to the current plot itself. The Holy Knights being just a bunch of incompetent pushovers needing constant immortality boosts to not fold immediately. Imu's big arrival feeling like Oda fast tracking him due to not having a proper villain planned out for this arc. Loki being another joiner bait to string fans along who will go in the same boat as Yamato, Carrot, Paulie, Wiper, and Vivi. The stakes being just rescue the kids, with everyone being fucking useless outside the monster trio. There has been filler arcs better than where the current story is at.
