It's not that hard. You just need a good fireteam. It took us 3 1/2 hours to complete the raid all 3 times with challenge mode. We started at 3:30pm est and finish at 7:00pm. Every week we get it done so raids are out of the way, giving us more free time to do other things in destiny or to simply play other game. Just get yourself a good fireteam. We do it as follow 2 Titans, 2 warlocks, 2 hunters every go. 2 Titans in the middle melting ogres. Platformers killing there Knights, hunters are tethering adds after staggering oryx. Platform ration same as no knight strat. Meaning 3 of is assigned to platforms 1-3. Kill shade rinse n repeat. Though we do one complete raid but grab warpriest check point between the two of us. Skipping that jumping shit twice.
