I too have been struggling with this mission. I’ve been playing with one other person trying to get through this so we can advance our guardian ranks. Unfortunately, we get as far as the boss level and our revives run out leaving zero room for mistakes. I’ve lost track how many attempts were on now. Please, a fix would be great.

Agree - its is simple awful and does not work, it utterly infuriating and the complete opposite of what good gameplay experience should be... and not a fun challenge, regardless of what Bungie might have intended. Everyone is avoiding it and making 25-30 mins, now instead of 20 is borderline insulting..15 mins extra makes no difference due to the negative modifiers and delta added to the original mission. Bungie Dev team, whoever is not backing down on changing this needs their head examining, this is now blocking the guardian rank up for many of your playerbase. Do the right thing and either swap it out as a master conquest and/or remove the limited revives and timer completely, negative feedback on this has been widespread now.
