i actually seen some potential setups given what's in their kits... i know the wind duo I pulled would spike your burst gain rather quickly on a wind team if you can cover your debuffs with your other hime and/or soul.
but that's more going from a viewpoint of my current wind hime anyway (and i wouldn't need gaia on my wind team if i'm not tanking hits so free space there).
most jewels went to rolling gacha... but even then, a lot of my space is already flooding with R weapons and enchancement fodder..
i should have roughly 50 in weapons i keep and roughly 30 in eidolons i kept due to a lot being event SSR eidolons
and yeah, i did roll a lot of hime weapons multiple times... if i wasn't an idiot and used some drag eyes on gacha tickets long before the awakenings, i'd be able to awaken another hime (Susanoo or Tyr)
