I agree with you OP when it comes to the fights themselves. I dont know why but it does feel a bit lacking compared to the first one.
I disagree about it being too easy. Balancing something like that is hard imo. I guess I got lucky and had quite a few people in the raid that already did it. Thus we did not wipe once. I watched some youtube videos from streamers and it was a wipe fest for some of them.

In the end, as you said, this content is meant to be run quite a bit. If its so hard that the mistakes of one group can bascially lead to a wipe it would get too annoying. Do you really wanna wipe again and again because one group is full of newer players while you are on your xth run?
