To me is sort of balanced, the only game I know that denies critical strikes is Smite: ''If you receive a critical strike, you cannot be critically striked again for the following 3s, and gain 40 Magical Power (Their equivalent to AP) during that time. The effect has a 20s cooldown.''

Giving both a duration and a cooldown should make it actually balanced, because the component that turns your innate passive's effects unbalanced (Beside free global stats :V) is the lack of internal cooldown.
