You are seriously missing out on some strong build options here if you pass up Divine Hunter. In exchange for Aura of Courage, heavy armor, and Aura of Justice, you get Precise Shot for free at first level, and eventually can grant feats like deadly aim to all your allies (including yourself if you don't have it.)
If you are a human you really don't need extra feat from Divine Hunter especially, when you lose almost all immunities you have(immunity to fear and charm) for it. I know you have high saving throws, but it cannot be 100% sure that you will succeed.
Generally speaking, DH have only Precise Shot,Aura of Care (Su)(almost Improved Precise Shot), Hunter’s Blessing (Su)(Oath of vengence have much better Su(Powerful Justice) then DH.)... for what? Only for feat saving. You have everything what archer needs (Point-Blank Shot, Deadly Aim, Precise shot, Rapid Shot, Manyshot).
I pay attention to your companions, when I compared. They don't benefit from Hunter’s Blessing, if they fight with meele weapons...
Since you are an archer, DEX based building means you will benefit from higher DEX bonus to max AC. You have access to mix Gloves of Dueling with Greater Bracers of Archery, and depending on your DM you could theoretically take the Weapon Focus and Specialization feats to vamp up your DPR.
Fighter 5 is a fantastic way... Bonus feats and +3/+3 for weapon traning(gloves of dueling)
It can be useful for you, pick Dangerously Curious trait and use wands for more versatility or buff party or self. See threads
