Yeah, it does get very frustrating, I spent all day yesterday trying to beat oryx. It was always that one person who always kept dying in the most inconvenient time or just not getting the mechanics down. Fortunately, I ended up with a group of randoms and we all just hit it off like long lost friends and after just a few wipes we straight up just owned oryx. I guess bungie is over compensating for the fact that crota was so easy so they made sure to make this raid a team effort and in this type of raid, you are only as strong as your weakest member.
