Xbox 360, ran with a group of Destinylfg.com to the Deathsinger today. We died a lot of times, but many of those "Rare" times you spoke of in your update happened simultaneously. At one point, I ran in, saw the shriekers for both sides, lured the wizards out, and once the wizards were dead? No shriekers anymore. Needless to say we didn't get through it, but I saw the update and I've done a lot of Crota Raids just to help people, but this happened a lot for a single group. We lost most of our heavy ammo and sniper ammo because of it. I am making this post as a waypoint for those who have experienced it to express their discontent about this. From the flawless raider achievement to simply wanting a structure flow to our battle sequences, these sorts of problems should be tested more thoroughly for the next raid. Just my recommendation. You can't have a raid group successfully do things right if the right components are not presented. This is not an excuse to cheese fights as well. Post here if it has happened to you, what console it has happened, and how your group was chosen. Maybe their is links if you group is in different countries and thus messing up the servers, ect.
