Ok, time for some maths.

Let's pick 's base AD at level 18, which is exactly 100. Now, let's compare the damage dealt by an AA with +  +  +  with what  +  +  +  does. No runes / masteries / other items are included.

First build: 300 AD, 55% crit chance. Second build: 280 AD, 70% crit chance.

Average AA damage with BT (first build): 547.5. Average AA damage with MB (second build): 574.

Basically, Mirage Blade offers more AA damage in exchange of less raw AD (meaning less ability damage). Seems like a good choice for champions with low mobility that don't rely a lot on abilities to deal late game damage. The only one of them on which I wouldn't always build it is, just because his Spinning Axes proc lifesteal.

Let's hope Riot includes this thing in the Marksman items rework like they did with Deadman's Plate for Fighters.
