Karthus Ult and Yuumi Interaction

Riot, i think you need to treat this as a teather like fiddle w. Make it to where it will do damage to her IF she is not on a champ before they activate it. Make it to where it DOESN'T do damage if karthus didnt activate ult before she attached to a champ. If karthus gets fed enough he can potentially one shot yuumi from full hp no matter where she is at on the map.
