Karthus is broken and why Edge of Night is healthy
He can just ultimate across the screen any time for free kills and does unbelievable damage 24/7 anyway. The reason I think Edge of Night is healthy for the game and shouldn't really be changed is to exist as solid counterplay for stupid champions like Karthus.
I mean it's a global ultimate that does damage. Literally almost zero counterplay, literally.

dont exist and im sure karthus is allergic to those.
