Skarner

there have been multiple case where Skarner's (E) does not proc on next auto. Example: - being chased running for life, auto kiting and throw E onto voli, Skarner auto'd but the stun didn't proc till the second auto. i feel as though skarner should auto cancel after throwing it onto enemy champoin. As a wanna be skaner main i feel as though this issue pops up way too often usually meaning death. please Fix the pokemon.
