One other thing about Five Headed Dragon, instead of doing the usual thing of running straight at him to pull, run around the edge of the room first and pull him from the back. Much lower chance of him getting out of control and breathing on everyone else while you'e trying to get into position, although since this is WOD it also increases the chances of one of the other tanks deciding you're going too slowly and pulling him themself. Once you've got him in position, you can move up real close to the middle of his hitbox, which will significantly reduce the distance you need to move to avoid his breath AOE.

On Cerberus you may want to check what group is doing what, as not everyone does the "ABC" method and a lot of groups just send all the DPS in - in which case one offtank will grab the Wolfsbanes and hold them until the DPS come out, and generally the other offtank will grab one of the chains along with a healer. Again, though, it's WOD, so prepare for people just doing whatever the hell the feel like and get ready to make it up as you go along - as long as Wolfbanes aren't munching on your healers and knocking people into the slabber, it's all good.
