This is a great idea except for the Goliath and Exiled Vex encounters. I feel like each would not reach their full intended impact on the player without being in a cinematic format. Also the vex encounter would become tedious unless there was rough terrain, traps, or enemy variety involved. Also the vex encounter could be improved if the goblins moved faster and could climb walls or if there was a way to prevent the already fallen goblins from resurrecting, such as maybe an intractable object like the Relic that one person would hold and on super would emit a large AoE attack that would denigrate the bodies of the already fallen vex.
