Micro stuns + video

Getting stunned like every time. I have every passive on stun treshold + support gem. Also i have no clue how ppl are even can normally complete Vaal Factory with all ranged mobs with so high attack and movement speed...
No increased attack speed, stun build up, movement speed for mobs in this map.
