PLD Gear Progression

[TokenHero]

Hey Guys,

I've hit a rut in my gear progression and am not sure where to go from here so any input would be beneficial.

As of now I'm sitting on,

MH: Curtana Zenith
OH: Holy Shield Zenith
Head: i90 Myth
Body: i100 Phlegethons
Waist: i90 Myth
Hands: i90 Myth
Legs: i90 Myth
Feet: i100 Phlegethons
Neck: i90 Myth
Brace: i90 Myth
Earrings: i90 Myth
Rings: i90 Myth/i100 Sold

I've been grinding atmas but, after 4 days without one I'm pretty much given up on that dream for now. I still haven't beat Garuda EX/Turn 5 either but, I feel that I'm geared enough for both just Duty Finder is too toxic of a place to get anything done. I have unlocked Levi EX and it doesn't seem too bad as long as healers don't fall off of the boat so would it be more beneficial just to farm that for the wave weap and then use the sold to upgrade it?

Lots of questions I know, but any help will be appreciated
