They did use Clemency during downtime, there's a gap between 0 Clemency during the whole fight and 0 Clemency during uptime.
They also used cover to tank the party stack with only 2 players.
Unless I'm reading it wrong, the DPS did 28% of the healing.
The death was a DNC death 30 seconds before the kill and snowballed into a second death. Also, that death was recoved by SMN.
It's a work from the whole party, not the tanks only.
Can we stop making up informations now?
