It scales off of 110% of his TOTAL, not bonus, AD

Considering Master Yi has 109.1 base AD at level 18, increased to 130.92 by the new passive on his E, Q actually has a base damage of ~294.

So, without any extra AD from items, masteries, or runes you are actually only loosing 6 damage by the time you reach level 18.
