Now I'm sure many people have often been frustrated when someone in their group mistimes a stun vial throw at Vanaduke and he instantly ends up swinging (though the animation doesn't happen) and they are then set fire and unable to move due to the stun of his swing.

Sure its avoidable if people time their stun vial throws but when it comes to using Stagger Storm on any other enemies, as soon as the status ticks onto the enemy, if they are charging an attack then they'll instantly attack and skip the whole charging thing altogether.

Surely its not right that a status that is used to slow enemies, in fact speeds them up on status impact.
