Kind of, when you activate you E you lose the passive AD when attacking towers.
The Double AD still affects your autos on creeps/champs...just not towers.
(Ex: I have 75 base AD and +25 from passive...I do 100 to towers and 100 to minions...then when you activate E, you do 75 to towers and 125 to minions.)
---This was most likely done to stop backdoor/split push Master Yi.
...I just want the ToolTip to say something like "Bonus AD is not added to basic attacks on towers."
