Random thought on buffing Sterak's without Marksmen gobbling it up

Basic concept: Rather than actually granting any attack damage (at all) Sterak's instead deals some amount of bonus physical damage each time you damage a target (can't trigger itself). Juggs, by and large, have a plethora of DoT and multi-hit abilities, so they would be able to take advantage of this passive. Since it wouldn't interact with Crit or Trinity anymore, it wouldn't be nearly as attractive on most Marksmen and Fighters. For tuning purposes, the bonus damage could be capped at (value) per five seconds to prevent it from being stacked too quickly.

With the major abuse cases curtailed, Sterak's could probably have its stats tuned to be less terrible.
