Am I doing something wrong with healing dungeons?

Also, on the subject of fluid aura, you can use it to extend your sleep past diminishing returns.
Repose (30 seconds), Repose (15 seconds), Repose (7 seconds), Fluid Aura (5 seconds) and just as its about to break from the bind effect, start casting another Repose, by the time the Repose lands, diminishing returns wears off and your back to 30 seconds. It's not often you'll have to pull that card out of your sleeve, but it's a darn good one to know how to use.

I think they removed being able to do this in the patch. I managed to sleep a mob for 30, 15, 7 at their full duration, and was unable to sleep again for the 30 seconds it took for my party to kill it.

True, I've only tested this on a couple of mobs so far, but it looks as though long sleeps have been eliminated.
