Oh yeah, I got killed or almost killed a few times by those vex cores by other players & I find it generally annoying. There are also players throwing glacier grenades in the vex elevator tube, causing other players to die & respawn to the beginning at the 2nd encounter area. And when they push the buzzer to start the boss, we end up getting tp'd to the boss, losing our starhorse favor buff for those who were lucky enough to get it. So apparently there are multiple ways in Dares that can kill your fellow teammates that can also jeopardized progression and ruin the experience.
