I have a bit of a love/hate feel towards King's Fall. The most irritating thing about that raid is how heavy it is on mechanics. There's very few moments where you could make a mistake and afford having a guardian or two down and have teammates pick up the slack.
The Oryx fight itself is very lacklustre to me. Everything else from the music to the visual aspects was quality, but the entire battle just felt like a chore more than a battle against a powerful King. Between him and Crota, it felt more rewarding killing Crota.
