my current wind tea doesn't have a lot of key kami, so using awakened gaia with a lot of atk downs can give quite a lot of sustain for your team. adding Joan to this combo makes you nearly unkillable when used right (bonus points with joan and gaia's mitigation skills combined practically nullifying damage at that point).

the trick is to use what you got to survive. if you can build more power on that to clear faster, then fine. but top priority is being able to survive the harder content, not smashing it into oblivion.

granted a lot of setups ignore using gaia, but you're not there yet and she's WAY more useful to players that can't crank out the damage, provided you use her right...

can't overestimate that powerful skill set she gets even when awakened or you'll find yourself in a bad spot, especially if it's something like a wind team against Rahab ragnarok since you're getting nuked often and it'll crack through defenses at some point.
