You can hide or show the info and/or the image of the operator. Being a 3 Star, she is cheap to upgrade saving your resources that can be better spent on other classes. But one advantage with Ansel is that at E1 he has a chance at healing an additional operator. It’s going be to a while before you reach that 6 Star end game squad.
You can also delay and stall out the absorb shield, or if the spawn is weak enough you can just use a nuke active to kill it. Damage reduction reduces the damage received from all sources except gravity or true damage.
