Haven't done Arcadion as of yet, but the difficulty's been a refreshing change from Endwalker.

That being said though, I do think there needs to be an acknowledgement that people can find some mechanics trivially easy, and yet also find other mechanics almost impossible to understand, even in the same encounter. For example, I can't do E7N Portals to save my life, but throw me a Flood Ray or Dominion, and I'll be comfy.

Also, it takes failure to get better as a player, and that's always been the fundamental truth. Every Hardcore Raider will tell you that they've wiped tens of thousands of times, and even caused their own fair share of those wipes.
