While I'm not sure about the first two, the last part should be >>>>>>>> Odin
Odin is pretty shitty. She's okay, but her Awakening basically only gave her Fortitude and nothing else. Still probably better than any SR, but basically any other SSR that you pull would probably take her place. And he already has Hastur, so...Because of Cu's Awakening, I'm not entirely sure that's the case. AW Cu is guaranteed 100 Burst after two turns (1st Abi +40, two turns of guaranteed triple +60), and after burst then she has her gigantic Trpl+ buff. With Tiara set, she should be... 5% base + 45% buff + 15% Tiara = 65% Trpl and 10% base + 15% Tiara = 25% Dbl. So you just need about 10% Combo rate from Accessories to guarantee Combo attacks, making Cu ridiculously fast.I just slap Combo buff on Titania herself, and give the person in slot4 the +30 burst buff. That way slot4 is guaranteed to be ready on after three turns.
It gets trickier if you have two slow Hime, like Gaia AND Hastur. Then you give Combo to slot3, which is probably Gaia and burst to slot4. That tends to make both ready after three turns, but then Titania herself probably isn't...
