Is there a reason why healers are running Volcanic Queen in m/eHBH? I saw healers running both Give Me Your Wounded and Volcanic Queen together. Isn't Give Me Your Wounded and CE enough?
GMYW alone should be enough. The only reason you would need more than that print is if you're running without any defense coabilities at all, which... just find a different group at that point.
If they're in the rather standard composition with a Choco Gelly and the healer themselves providing the 20% defense boost at the beginning then it is practically impossible to not pass the HP check with GMYW. You need to get over 2200 HP in that case and you can do that even with a strength dragon and no augments by a pretty significant margin.
I think the most recommended second print on Jiang Ziya (since Thaniel obviously needs Chocolatiers) is The Bridal Dragon. It can give you the extra dragon gauge needed to let someone dragon tank the second stack if the party isn't good enough to break before Mulspelheim. Then in Master the dragon damage pairs well with Leviathan for the bog on break strategy. Beach Battle is another good option for the second print for some skill haste and the buff time will get you can extra tick of healing off your S2.
