Start off with jumping when available (no fires) off the ramp and go to the first boss. DPS him real fast and move on to the next boss. Do the same thing here and once you kill him be prepared at the door to reduce around two seconds. In the next part try to go near the door at the end of the tunnel as fast as you can, but first make sure you survive. Once you kill this boss go on and start killing the Worgen with your tough spells.
