I think that it'd be a more balanced feature if they limited the amount of people that you can treat in an instance, and if they included a diminishing return feature. You can only bandage a wound so many times before it's not doing anything to help the healing process. Maybe keep the removal of the wounded condition but have a cap on the amount of health regained from the feature. It remains relevant to keep the players from dying, but it doesn't encourage taking large amounts of time to just heal to full. Limiting the amount of players just kind of makes sense too, since it's ridiculous to think that mundane healing can cover 6 patients in 10 minutes.
