Usually the best episode of an anime is mostly in its climax episode, but the build up along with the preparation that a lot of the different guilds and party member, all the way up to higher ups and officials give a sense of urgency or stakes to the upcoming episodes later, which I think is super important when it comes to establishing the climax for a season. A good payoff to me in my opinion, comes from constant properly paced buildups before it. Also it gives me the feeling of the Chimera Ant Arc from HxH.
