Personally I think it's perfect as now it once again simulates the character's own field of view like all the other NPCs, while actually balancing other light sources such as Torch and Light Cantrip which illuminate the area around the character fully. Maybe they could just have a slight longer fade-off on the edges, but otherwise I think i't's perfect.
Wasn't a fan of the circular Darkvision at all because it looked silly to have a character acting as a lightbulb and especially because it ruined environmental lighting. It went from being a field of view to circular illumination to entirely globally applied illumination.
