It does require people to know what to do.
The first one I queued into was a failed one with 15 mins left and people bailing left and right.
The second one, we killed it after 2 wipes. First attempt, most of us didn't know what we were doing. Second attempt we almost made it. Third attempt, we smooth out the remaining rough edges and manage to drop the boss.
Very fortunate that there were some there who knew what to do and was willing to explain, in addition to people who could follow instructions and pick it up what needed to be done.
Not a fight that could be derped though.
