That's 3, maybe 4 Water himes you're suggesting! I'm not looking to build a whole new team from scratch, just fill in holes for the time being. Though since I did just get Leviathan I can certainly see my Waters getting better. Took a quick look on the wiki at Shiva, and her AW does sound really great. She's a looker, too. I could definitely consider her, but if I need to get another 3 other girls to make my Waters shine then maybe I'll hold off. I only had one Wind SSR earlier this year (Gaia), then out of nowhere they all started falling into my lap. Maybe the same could happen with Water. I've rolled Ryu-oh's gun like four times now...
Anyway, if I were to grab Shiva, what team formation would you suggest with my current lineup? If it just doesn't really work, or if there aren't any suggestions for my Darks or Winds then I'll just go ahead and grab FMammon even though I don't have a good Eido for my fires.
EDIT: And I just wasted money on the nutaku winter special for $100 to do the Miracle roll. The rest went to the Christmas gacha. Got a 5th copy of Behemoth, a 2nd copy of Sleipnir, an SR I didn't have, and 2 Rs I didn't have. None of them were the Christmas hime. So that's a total of 6120 star coins and 15,000 jewels with no new Christmas hime. Rate-up is a lie. A terrible, horrendous lie. All I wanted was Charis, dammit. I feel like even FGO rates are even better than this.
