It's not hard. For the amount of people that don't complete this strike it has the most hiding spots out of any end boss there is. Also staying together as a unit under right platform is a great strategy. Bring void weapons for Psion flayers shields. Bring word of Crota or maxed void shotgun. Ice breaker. Heavy with surplus. Bring one voidwalker. Or a titan ward of dawn. Gunslinger optional. Bladedancer is terrible choice. Safe zones: Immediate boxes at top of outside room ramp. (Directly there where you meet the two legionares) Behind boxes to right of Valus spawn. Behind boxes left of Valus spawn. There is no shame running and hiding when in trouble. But STAYING THE ENTIRE TIME WOULD QUALIFY.
