Imagine if they made it a scenario instead. A really cool one too. For example, they could make it so you climb on Gorgorek all Shadow of the Colossus style instead of just hitting him as he tickles you. They have the tech to do this, so it could have been done and it would have been great. Also, I would have saved Azuka for the Iron Citadel or something. If they REALLY wanted her for the scenario though, they could have added a few more mechanics and added a bit more flair to the fighting area.
