The Divine Hunter's Divine Bond opens up the options for ranged enchant effects the standard divine bond does not.

If you're focus is on Archery, heavy metal is probably not a preferred option given that you're not a fighter that can ignore the speed drop.

In my world if you see a company of elven archers, a divine hunter is probably their commander.

Would I expect this to be a common archetype? No. but it's a pretty decent execution that fills this particlular niche in the paladin bestiary.
