[Suggestion] Make Karthus Ultimate Voice Over Global

as a small amount of players who still play the champ enjoy his great V/O I personally feel as if making the voice over that karthus says from local to global.

This would give greater impact to those who suffer the fate of the almighty requiem that much stronger hearing the final words of you slayer sing you to your demise.

I feel as this also fits well with characters that already have music/ v/o lines spoken to everyone when someone activates their ult (such as sion, kled, talyiah and many other champs and skills that do such this.)
