Look, whatever you do do with bow, you can't go wrong... except full int, but even that has a potencial.
People argue all the time what build is best for bow, but seriously, those are useless discussions. Do whatever you want. You can't go wrong.
If you add int, you'll do more regular dmg and have more mp.
If you add str you'll do higher crit and have more hp.
And that's the whole philosophy. Anything more detailed is just unnecessary.
