Karthus Ult should have sound

well i posted about this before but i dont think it caught much attention..anyways

I just wanted to share my idea for karthus. Well the point is if his ult is global shouldn't his voice be global when he ults? just like or or even .

i mean what would be more awesome when ulting and everyone can hear him say "What's the incantation again... yes, erm... oh, right, R" and those with the pentakill skin "You can't kill the metal!"

its just an idea and would be great if it was taken into consideration
