Headhunter Caitlyn missing "headshot readied" animation/sound.

As title. When you fire your sixth shot and her Headshot passive is primed, Caitlyn's classic and Sherrif skins at least (likely others too) have an animation and a sound effect to signify she's all ready to headshot.

The Headhunter Caitlyn skin doesn't have a clear animation or sound effect to signify she's ready to headshot.
