Varus' disappointing buff

AS is a great thing to have as an adc but only gaining access to it after your target is dead is kind of a waste.

My suggestion: Passive - Blight Percent damage increases as you level up, similar over all scaling.

W - Exacted Vengeance Gain x% AS per stack of blight consumed up to a maximum %, lasts for t seconds, duration is reset every time blight is consumed. Scales with ability level.

This gives him access to the buff based on the management of cooldowns and blight stacks, which IMO is a much fairer and more useful way to grant AS.
