I'd say "no". If I can identify the deer with my good binos, I can generally still see the reticle in my Leupolds well enough to make the shot. That being said, I've grown to like the little dot in my Trijicon scope and used it a few times this season on late shots. I probably could have made the shot with a non-lit reticle but the dot makes it a bit easier. I could really see the illumination being handy on black hogs at dark, as I just need to get a bullet in their front end, not identify their headgear or precise body angle/presentation.
