Yes, I've noted that using 20% HP Eidolons is barely even an increase to my HP as it seems to increase my HP modifier from 200% to 220%. And my god I'd love to use double Elemental for this fight bloody everyone and their mother in my friendlist has moved to Dullahan, so I'm kinda stuck with Crom's Crotch and Cthugha.

So anyway, by ye gods I hope that we get that Eidolon on Nutaku. It has good stats, and most importantly, I want the Himes that accompany the event.
