It depends on the difficulty you're playing. On adept, using a bound bow with maxed archery and all damage perks, the healing amount exceeds by only a bit ( yet observable ) the arrow damage. Here i recommend using a long bow with iron arrows. On master difficulty however, the damage done is divided by two, but the healing remains the same. From personal experience this build does not have much survivability on master, unless you go into alteration for the atronach perk and the atronach stone of course.
