The Transition I made from shooting fingers to properly working a release was the hardest thing I have ever done in Archery, and I am sure shooting fingers for 25 years before making that switch had a lot to do with it.
Shooting traditional with fingers was Great! Even shooting fingers with compounds for 12 to 14 years was fine, but as compounds got shorter and letoffs got higher it became harder and harder to get a consistent clean release.
I am sure I could shoot my current bow (with a little practice and a good tab) with fingers good enough to harvest game but I really like being as effecient with my Bow as possible, and Murphy's Law seems to always be close by
