Hi, I'm looking to get the SSR guaranteed Gacha but can't decided whether I Should get Dark Amon/Susanoo or go for a different element.

Currently my Dark team has Satan, Hades, Osiris and Dark Amaterasu. Is it worth getting Dark Amon/Susanoo when I have these 4 SSRs already? I also have Beelzebub as part of my Dark team.

Other SSRs I currently have are Tyr, Ea, Snow Raphael and Sol. Since I have 2 Water SSR, I was thinking of maybe getting a Water Kamihimi, Cthulhu or Ryu-Oh?
