Karthus ult does a lot more damage because of the fact that ability scaling and magic penetration exist, and global presence is worth more in league because fewer people have it.

Zeus, like every mage in dota, will eventually fall off in damage because he only has his base damages to rely on and no way to scale his spell damage. Karthus is the opposite: he scales absurdly well.

Also, if we're just talking about the ult: there are a lot more ways to counter a Zeus ult. Dota has items like BKB, league doesn't.
