Well would you rather die on a nightfall at the boss fight and wipe? Or self res and revive your team when they die trying to revive you? Sure you can go invisible but enemies still shoot at the dead bodies/floating orbs so you'll still take damage and possibly die trying to revive someone I mean I can still use my super throughout the strike or raid and it's not like I TRY to die just because I can self res. and I don't self res unless my team does and we're about to wipe
