Does Strength increase Bow Damage?

I just started a bow ranger and was wondering whether I should take the Strength nodes. Pressing 'C' I read that every 5 Strength points increases my 'melee physical damage'.

Does this all increase the physical damage of my bow?

If you use Iron Grip in the passive tree: Yes.

what evilknivel said and.

bow = ranged, ranged != melee, bow != melee

So how would you think that "Increases melee damage" would work on a ranged weapon?

Strength will give you base +hp too, which will multiply nicely with any life% nodes you have. Not a ton, but it's worth remembering that. So if you're doing a physical build and want extra life, strength + iron grip isn't an awful way to go.

Original question's been answered, but yeah. Obviously a bow isn't a melee weapon, so strength doesn't impact it at all unless you pick up iron grip.
