My bad thats what I meant that you need a fire team for the next tower. Yea wind team is relatively new because i just pulled those 2 ssrs with magic jewels. So I'll have to do some skill level upgrading on that first to get it ready.
The problem with my thunder team is that even though I get so many bursts with shingen they all just die from their 10-11k max hp. Thats why I'm just considering to be done with thunder and move on to something else.

Can you tank the rage overdrive from the AQ 5 boss with Awakened Gaia? Because that would be enough of a reason for me to want to get her, otherwise I would probably be leaning to either cybele or svarog.
