How to get through Titan’s Earthen Aegis shield?

I see people online say it’s either weak to wind (which is just false) or to just power through it with Synergies and Limit Breaks, but I simply am not doing enough damage fast enough before Titan party wipes me with Earthen Fury.

I think I’m struggling with the pacing of my moves. When should I be deploying which moves? Doing Full Might as a challenge at Level 22.
