Iron Grip Keystone Wording Clarification

I believe a clearer wording for Iron Grip would be "Strength's Damage bonus applies to Projectile Physical Attack Damage as well as Melee Physical Damage"

I think this is clearer because the Strength Damage Bonus doesn't apply to all Projectile Attack Damage, only Projectile Physical Attack Damage.

It could be argued, "But the Strength Damage Bonus is only for Melee Physical Damage and the player should already know that". So that should be added to the wording as well.
