Increase min revivr damage to 40ish, but charging the revivr doesn’t add damage (it only increases revive hp). Also, make her damage dropoff start somewhere in the 30-36m range. Finally, make her battery drain rapidly while at full charge, so she can’t sit on a full charge shot. Essentially, this would give her a pseudo-pdp/grandeur instead of a pseudo-moa. She would be slightly less abusable at high levels, since she can no longer one shot most mercs. However, she would be somewhat stronger at lower levels, since she wouldn’t be reliant on landing that one fully charged headshot. This would also be relatively easy to implement, since it is mostly a numbers change.
This would also nerf her reviving significantly. If she can’t sit on a full charge shot, she needs to spend a second or more charging before reviving someone, and then the revived guy takes another second to stand up. Depending on how long it takes to hit full charge, her revives could start to approach phoenix self-revive levels of delay. At that point, getting her balance right ought to be a matter of tuning some numbers.
This might end up as an overnerf in some ways. However, if she does end up too weak, buffing her back into relevance is a lot easier than trying to balance an inherently overpowered kit.
TL;DR: 40ish min damage, damage doesn’t increase with charge, damage dropoff starts around 30-36m, battery drains rapidly at full charge.
