"It's wonderful early, but late game that 3 second channel time does nothing for you in a team fight. The only real time you could use it is during your passive... which means you're already dead."

Thats why you don't use Requiem in Team Fights. You use it to finish off enemy champions that managed to escape the fight as it ended. Using Requiem just because you died is about as dumb as trying to use it during a team fight.

The other option, which has worked greatly to a team's advantage, has been to use Requiem at the same time that your Initiator is starting the team fight. Which severely weakens the enemy team going in.

Sounds like you tried to play Karthus and failed miserably.
