Karthus QOL: Luden's Echo tells who it will hit for his ult

Hello,

So, Karthus' ultimate currently targets the 'first enemy champion' who is picked for Luden's Echo, but this is not only counter-intuitive, it's downright cryptic. I think a good solution for him, and others like his ultimate, would be for the Luden's Echo tooltip proc to state "Will hit X champion when Y ability is used at full charge" for that specific champion.

Thank you.
