That passive is just way too OP. 100 range is nothing for reducing duration of not only disables but all debuffs and DoTs by so much. Malzahar's Malefic Visions for example will have its entire duration reduced to 0 after only walking 300 units, which at base movement speed takes a little under 1 second, meaning that he will only take a fourth of the spell's damage.
