Massive damage and teamfight presence.

9% attack speed, 10 ability power or 6 attack damage

When you enter brush, a poro appears. It will stay behind to give you vision.
Thanks to the slow from Ashe's passive she's able to easily stay in range to proc the bonus damage.
Overheal is an all-around great rune choices on most AD Carries. The shield while small, negates a lot of damage over the course of the game.
Legend: Alacrity is the go-to on pretty much every AD Carry, especially Ashe who loves to auto as much as possible.
Coup De Grace pairs so well with Press the Attack's bonus damage and is more reliable than Last Stand when you have healing.
Of all AD Carries Ashe can abuse Cheap Shot more than any other. Her auto-attacks alone keep them slowed for free true damage on cooldown.
Ghost Poro is an excellent way to provide reliable vision to keep yourself safe during the laning phase.
