As you can see on the video (especially towards the end), there is a growing delay between when her auto attack hits a target, and the time it takes for the passive to proc on the target. From what I've seen, this grows larger and larger the more she hits the same target. It actually cost me the battle in this case, but I think the only thing that needs to be changed is a timing adjust on the passive proc.
That thing with cost you the battle is an overreaction over the loss(RB Kassa beast mode; shield was too big to pop), but the observation is legit. It's true in other cases can make or break a game. Also, since it's an autoattack/ procc discussion, other champs experience this as well, not to say the attack animation cancelling for some of them when they're about to kill a target with next auto and the target dies right before the animation starts, so the whole auto attack process is reset, resulting in a dps loss. (-_-)
