The damage reduction is affected by both attacks and abilities. It's essentially an anti-carry ability.

I agree with you on the the Q. Remove the knock up and add the cooldown reducer through autoattacks. It was one of the main reasons to build AS apart from the ultimate and passive.

Thanks for the feedback :)
