So I was pointed in the direction of the Best SR team thread for an idea on what SR I should select using my Miracle Ticket, and after some browsing through it I'm down to the idea of shoring up either my Water, Wind or Light rosters. Thing is though, I'm not too sure which side I ought to shore up and who to pick up for it despite having some ideas now; I'm inclined towards Light since they're unresisted by any element (still need a good Eidolon lead, but Barong is in the epic quests now) but am not too sure if that's my best course of action. My SR/SSRs for those elements (and a couple of Rs, minus the 4 story SRs) are as follows:

Water: Aphrodite, Belphegor (and I see Gabriel's related Epic Quest is available, can unlock to get her)
- Considering Venus
Wind: Guan Yu [Aisha], Hermes, Freja, Heimdallr, Oberon, Cronus, Maeve, Caspiel
- Considering [Songstress of Flowers] Ramiel
Light: Demeter, Belobog, Attar, [Sunlight] Brynhildr, [Lunar Glory] Caspiel
- Considering Diana

Another thing I scratch my head over is that I've seen talk of unique weapons for the Souls a few times around here now, but I don't think I've seen their Quests. Where can I find them?

Thanks for any help in advance.
