Don't know if this was intentional or accidental, but I've noticed that after beating Seerus there are no hearts spawners before the elevator like other bosses.
In cases where a group barely finished, with any players dead at the end and other players with less than one pip of health, if no one has any health capsules left, it is then impossible for anyone who's dead and needs a revive to pick up the material unless they revive with energy.
Not sure if this was done intentionally, or if there are just no hearts for the sake of style after the fight.
Just... I was with a group that was ALMOST there, the last living player had JUST enough health for to revive, and it really stunk to be on the ground and someone willing to revive but not sure if it would be possible.
Initially I was going to wonder what the point would be, but yes the fact that the material needs to be collected does factor a lot into it so I can see the need for something like this.
