Oh, haha, that makes sense. So Poseidon's party zeal offers more to the party than Hastur's def down and party atk up? I thought her skill set looked a little underwhelming. But I could give that a try.
I can't really speak much about my himes dying, since my weapon grid is still awful. I only lucked into Hraesvelgr and all of these SSRs recently (seriously, like 4 months ago Gaia was my only Wind SSR, then all of a sudden - BOOM. Winds out my ass from off-banner pulls) so the grid needs a lot of work as I'd been ignoring it until I got all of these. Even without Managarmr my Lights still blow this out of the water right now, so I'm hardly using it.
