His Q has 1 second cooldown and can hit entire team for a lot of damage. His E does that same thing but you don't need to aim it, just stand near your enemies.

You probably saw many situations in which enemy champions escapes with flash with just a sliver of health. That is where Karthus shines, there are no stragglers when you have Karthus in a team.

Even if he dies he will then start to dish out a huge ammount of damage to anyone caught.

Problem with him is teammates, if your teammates are bad you won't be able to do much for them, if they have at least half of their brain, then karthus is a free win.
