I think his passive is okay, but seems rather situational. Mostly used when he's in Drain mode or charging up for ult. Even then, the MS boost is still at a paltry 1.5sec with 25/30/35/40% boost. Not exactly the greatest at chasing.
Can we up the MS boost to 2seconds and have his Q (Fear) proc it as well? Would make him seem more like a terrifying scarecrow coming for your biscuits.
