Oh no, I just got Cloud's Awakening scraping together mithril from the gifts and new event.
Are you using two healers?
I've tried a few setups, none successful yet so it's very possible I'm just doing it wrong and maybe Cloud's awakening is amazing here if used differently.
Anyway, my best team has been:
Zack -- CSB and imperil BSB
Bartz -- Awakening and.... some combo of USB1, USB2, or BSB (wind).... not sure yet which is best pairing
Cloud -- Glint+ and Awakening
Eiko -- USB1
Relm -- USB1
Part of the problem is that you need both hastega and dispel, and none of the classic wind dps can slot in dispel or banishing strike, which means you basically require a double healer setup, unless you go 1 healer with dispel+haste equipped, leaving them unable to actually cast anything except soulbreak's, which would require an entrust battery..... then you're back to 2 slots for healers anyway (effectively).
Even with Zack's chain, Bartz awakening can't break rage when it's at level 3, and sometimes not even when it's at level 2. Because it takes SOOOOOOO LONG to get two soulgauges, even with lifesiphon, the boss is always at rage3 when the real dps starts. Cloud with Glint+ into Awakening (putting him at 3 en-wind stacks with his LMR) can trivially break rage, even at rank 3.
Once Cloud's awakening wears off, that's basically game over. I can't re-cast it, and I can't reliably remove rage anymore.
The obvious answer is to just win before the 15 second awakening mode runs out.... but if I don't use Cloud's awakening really early in the fight, rage goes to 3, which is near impossible to survive. So I use Cloud awakening asap while Bartz is busy filling his gauge, eventually Bartz gets his real dps online during the last few seconds of Cloud's awakening, I chunk a lot of health off the boss, then Cloud awakening fades, boss goes to rage 3..... GG
Nearly all the videos of the wind odin use Cloud USB1 + en-wind stacking. When Cloud's USB1 is about to fade..... they just re-cast it. That means Cloud always breaks rage with every attack through the entire fight, leading to a victory.
