Turrets for heals doesn’t work very well, it was tried in experimental.
I’d say make her secondary fire heal instead. Buff her beam a little since it’s be her only attack. The support passive would help her a lot.
Buff/change her turrets a bit so that she can create a nest for herself to help counter flanking like her original build. Or replace them with something else entirely that gives some other team benefit as a support. Maybe overshield generator, but it’s got limited range so it’s not just permanently boosting the team like the old ult one and is something you put down to reinforce a team during a fight that can be destroyed, but helps with something like pushing through a bottleneck (but once you’re beyond that bottleneck you’re out of range again anyway and it has a finite lifespan of a few seconds, maybe 10?)
There’s lot of ways she could be revamped as a support given her hard light concept basically lets her do anything.
I think they should lean more into support constructs. Like a hardlight barrier that acts like a mini icewall against foes, providing temporary cover (like 1.5-2 seconds) for repositioning or protecting against a burst of damage.
Her ult is a good support ult, but teleporter back to her ult but let her place it anywhere on the map so she can reposition the entire team and attack from a completely different angle.
There’s lots of things that could be done and honestly support is the better place to put her for it
