I was thinking if WHM could cover the AoE Esunaga, but I also noticed the posts about SGE struggling too. The DPS to heal niche is kind of too weak now from what I am hearing about them. Just a glorified SCH fairy limited to one target as others have said for the strength. Soteria and Philosophia definitely needs to grant either a stronger effect or better heals to be more worth it from what others are saying. I won't say no if the majority decides the WHM fits best for Esunaga. I am just thinking of what would be fair for SGE too. If we can come up with other things for them, it may still be okay to let WHM have it.

As for the Spirit Link Totem effect, I was thinking of SGE fitting the doctor feel the best out of the 4 healers. It's may be a bit flimsy on the lore effect, but the best I can think of would be those IV Blood transfusions. Except in this case, it would be borrowing someone's life aether or something and donating it to another who needs it most. If we do place it on Philosophia, Soteria could be the SGE to Kardia link for sharing HP too. We'd probably have to include an effect that breaks the link when the "donors" reach 10 - 30% HP just to be safe. Although SGE should be more than capable of exploiting this effect with Ixochole, Kerachole, Physis, Pneuma and Holos. Consecutive Tank Buster hits definitely become a lot more smoother to heal with the whole raid potentially sharing their HP for the damage done. It could perhaps be another strong niche.

As for the Piety remark, I also avoid that stat too with my current casual play. For obvious reasons of course with very few of the Savage Mechs we are talking about. The "1HP White Hole" I only remember from a certain spoiler story Trial at the end of Endwalker. If the stat also did some other things like improve the healing done and boost the shield amounts in addition to MP regen, it might be a bit better. Although just a bit now since we are already talking about the extra healing not being needed yet. We'll have to increase encounter damage first before that extra suggestion starts to look more valuable. We may not need to nerf the tank and DPS self heals or party mitigation very much if the encounters actually damage the party consistently. The dance mechs have their place, but it's become apparent that the devs are relying on them too much. It mostly amounts to occasional cheap shots on first timers or lagging players with the healers mostly needing a raise or 1 oGCD heal to fix it. There are times everyone gets hit, but that is quite rare and players tend to notice and share where to go after a wipe. If a solution cannot be seen immediately, there would usually be enough veteran players who did the encounter already present to follow on where to go. It also keeps the easy stuff easy (solo hunts and FATEs) if we don't have to nerf the self sustains much.
