Does Karthus scale?

Yes. Karthus is one of the best late-game champions in the game.

Global-ultimate exception. Very strong late game and forces the enemy team to itemize against him.

The grade measures one thing: how much a champion can influence a coordinated late-game objective fight once both teams reach full builds. It does not measure early strength, snowballing, or win rate. A weak late-game champion still wins by ending the game first, which is what the rest of the library teaches.
