You're absolutely right. BT was just so deep, it really was a fortress fit for a corrupted demon. ICC I'd say captured the lore behind it well. However lore seemed more rich back in BC, so there was more visual depth put into the stories, meaning the raids had to compare.

Been there since BC. Was supposed to be a landing area with an alternate entrance but it was removed.
