I wish people would stop holding the chains on Cerberus until they expire because they want that tiny bit of extra damage. This is not some bleeding-edge Savage content where we need every second of spare DPS to make the enrage timer. It's World of Darkness. He's more than halfway dead already. He'll die seconds into the second unchained phase. Just chain him back up so we can get on with it. Don't hold the chains and let him get up and start buffing up and one-shotting everyone. It's just wasting time.
