It's usually found with high ping, but even Japanese players are having an issue with the new content because of faster and overlapping mechanics.
Any and all design issues with the new content can be fixed with better netcode. The challenge would be seen as fair (improvable with practice) rather than unfair (random and not responsive to skill) with zero change to the fight design itself. Otherwise, changes to design would have to be made to reduce the complexity of mechanics. As a certain other poster said, we have had easy content for "two expansions" (actually longer) because of this. For Dawntrail, the dev team decided to remove their old precautions. The above problems are a result.
