Sub Zephyr for Freya. Forget about Odin. You'll want to use Andromeda for most content to make up for lack of heals. The type C ATK debuff from Zephyr will greatly enhance your endurance.
Odin could work well with Titania, who grants a type B ATK/DEF buff. That would cancel out the DEF debuff. Otherwise, without a means to cancel out or cleanse the DEF debuff, Odin would be a liability. But overall, Odin is just a weaker version of SSR Cybele. You can tell the devs had a concept for Wind as a Burst-heavy element, but the initial implementation was pretty flawed.
