Replied a long time ago but just wanted to state that my feelings haven't changed. I think the concept of letting new players watch and experience the dungeon closer to as intended is best, and at the point that SE can provide trust/AI to run the dungeon instead then the reward will be lowered and it wont be worth most people's time. The reward is substantial (although one of the dungeons offers a lot more than the other, would be nice if they were closer lol).

That's not to say I can't see how it can be frustrating for others, an hour with most of it cutscenes can be a bit draining but it's not a mandatory content piece at least and I still think it's the best solution for the circumstance (that it's not ran by AI for example). New player's experience priority, and as a reward old players get huge and easy exp / tome rewards.
