Auto-play champion specific taunts on kill

Noticed with the recent release that some of his champion specific taunts were reserved for when he killed people. That got me thinking; why not make all champion specific taunts auto-play on killing that champion. I love playing and if anyone knows the rifts one true dragon; they know he has a lot of amazing champion specific taunts. Unfortunately it's quite difficult for me to walk up to an enemy to tell him about my "extreme feelings of happiness when he's not around".
