This notion that only allowing one respawn per person is needlessly frustrating. It's not prevalent in any other raid, goes unmentioned, and pads out the gameplay rather than making a fun fight. If anything, at least add something to the UI to make it more apparent, like an actual token system. I don't get how someone could program such a fun, interesting, and excellently-made teamwork-based raid, and have it come to a relative screeching halt with one shitty mechanic.
Please change this, my fireteam and I genuinely want a memorable raid experience, not a migraine out of ill remembrance.
