Unfortunately right now she's not real good
Dogwood will be broken.
Eventually we will get a 300% light gauge. You got 150% there with Dogwood and Mei.
I see you have Ghostweed. She will be on that team with 70% solar blast increase
Get a couple more 6* solar girls (light gauge, solar blast increase, Shine Crystal drop rate) and you will get bored with the obliteration of the enemy so easily and long for a defensive struggle again.
