Simple trick to jungle effectively
If you are playing a jungle champion with a disrupt such as Vi, Panth, etc etc, time your disrupt at the beginning of the jungle monster's attack animation. You stun him for the duration of one auto attack while avoiding an auto attack. So basically you negate 2 auto's. This may not make a lot of difference late game but during your early clear this could be the difference between surviving an invade/having enough hp to gank.
