Hey guys.
If you want a faster run during the "Nightmare event" after killing cookie, you can skip the werewolf event before the ship by doing this:
Wait for the door to open, then have a rogue/mage/night elf or anybody with a combat reseter run in, engage the mobs that's attacking the npc. Just attack them for like 5 seconds, then run back towards the gate and vanish/invis/shadowmeld, and the mobs disappear and you'll be able to just keep on going and engage Vanessa Van'Cleef to finish the dungeon :-)
Enjoy!
