I was thinking. How about instead of making shots go through full hp team mates, that when she hits a full hp team mate, but she also needs health, that projectile redirects back to herself, allowing her to get the healing?
In a way she would still need to make a “skill shot” but she would essentially be relieved from sacrificing her nade to get out of sticky situations just to self-heal.
Also Jeff, if you’re reading this. It’s time. Make Ana Wall climb
