Making it unskippable for everyone is a dumb, dumb move. Not even all the new players will want to see these cutscenes. Forcing it upon them is not the answer.

What they SHOULD be doing instead is, upon unlocking these dungeons, warn the player that the two dungeons are very story-driven with long cutscenes (much like how the game warns us at the end of 2.55 and such that a long cutscene is about to commence) and encourage use of the Party Finder to find like-minded people that will actually let them watch the cutscenes and not just bum rush the entire dungeon, to give them a more authentic experience (and even teach how to use the Undersized Duty option, if necessary, such that you don't NEED to get a full group of 8).

They really don't emphasize use of the Party Finder enough, and IMO this would be a perfect opportunity to teach players of its existence and what it could be useful for. Instead though, it's being squandered with bad adjustment decisions
