As said, I understand that you can apply realism to it, but it doesn't feel realistic, and it most certainly doesn't feel designed to be a realistic hunting sim. Even if I play the patient hunter, have got the right gear to reduce detection range, and wait for the perfect shot I'll still see the doe 'sit' with its head halfway into a tree or meander up and down a sheer cliff.
My only question is if we're going to see some improvements to the way animal AI behaves, or if this is just something we're going to have to deal with.
Yes, one day. It's not a big priority, but there is an AI pass currently worked on though.
