A druid in decent gear can easily solo Anzu at level 80. Kitty prowl all the way to his room and then clear the mobs inside it. Make sure to only pull a pack at time as they chain fear and when they are hitting you in the back they can kill you. Clearing the trash is actually harder than killing Anzu. Killing Anzu will save the group to the heroic, so you are better off solo farming it per druid than bringing all five in at once.
