Then revert the barrier HP and shield bash damage nerfs. If the real issue was her healing, undo the “fixes” that didn’t address the problem so she isn’t left with a kit that’s been stripped down in every possible way. She will lose a lot of survivability from being unable to heal herself while essentially turning into a pure “tank.”
Or give her the combo back and make her a DPS lel. People won’t be happy with her no matter how she’s changed or how bad in actuality she gets. All people will ever see from now on is the hero she used to be. It’s the same thing that happened with Symmetra except the perception of her was UP rather than OP.
