Maybe I'll max Poison Arrows sooner rather than later. I was going to look at that if I started needing more single target damage, but so far that hasn't been too much of an issue. It could come in handy for boss type opponents, though.
Battle Rage, Bleed and Life/Mana Leech skills only apply to melee attacks. The leech enchantments can be put on bows, though, so I assume those will work with ranged damage (I've always gone with Increased Damage and Increased Magical Damage, and if I started getting 3 enchantment slot bows I doubt either leech would be my next choice).
I never tried Ranger Surprise or Confusion.
