I love dungeons that features huge open areas, I also think the bosses are pretty cool although I admittedly hardly figured out what the 3rd boss was about as he died within less than 30 seconds since all members of the group were 925+ That said from what I figured out it seems it could be an interesting fight on higher mythic+.
My only real criticism is that I wish what a part of the dungeon would've taken place inside the temple rather than just the room with the last boss being indoors but thats really a minor criticism, overall it is to me one of the better dungeons they've released.
