Lowering the cooldown of his double damage autoattack doesn't mean much. His attacks just don't do enough damage for the cooldown going down 2 seconds to matter; even when you build strong AD.

NFD, you should stop assuming that I know nothing about this game.

EDIT: Ha, I was mistaken. It's not double damage, it's bonus magic damage that does at maximum 112 + 10% of his bonus health. I think it's like 300 bonus damage for the build above. I think that's hardly worth devoting your entire build towards, especially when the attack speed may just make it happen slightly more often.
