Get Esscence Reaver for the Mana Sustain and then just build absurd amounts of AD. With a shield that will only have 3 seconds of vulnerability due to cooldown, and scales off of 80% total AD.... might as well get a BT to have a second shield on to cover for those 3 seconds and have one of the most absorbant shields in the game for no defensive items.
