I believe shooting offhand is such a great skill/talent to have in real world hunting conditions. It makes it feel like cheating when you have a rest and makes quick offhand shots in the field feel natural.I don’t shoot far enough in the real world to see an issues. I do take a few free hand shots each session though
If I had to attribute most of my hunting success (with a firearm)to one thing it would be the ability to comfortably shoot offhand. (I am talking about <200 yards)
