Fluid Aura I tend to always position myself so that if I do gain agro and a mob runs at me I will push it straight at the tank and it will end up next to him. As for repos if I see tank getting extra damage I will heal through the first time then start sleeping mobs... usually one at most. If they break the sleep no prob if it lasted for all of 5s that's 5s of no extra damage to the tank. And I do have a sound macro for sleeping as well so that everyone is aware of it.
