Am I doing something wrong with healing dungeons?

No need to tell which one is slept. just push it out of the group and sleep it as it is rooted. If they hit him out of the sleep more than 2 times they would ignore callouts anyway.

Good tip! I would only recommend using the Push back (Fluid Aura) when dealing with MRD tanks though, Newbie GLA get a little panicked when things are out of Flash range.

I would still recommend the emote macro, it doesn't slow you down at all and it informs your group of exactly what you are doing (less confusion is always good). It's really all pro and no con.

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.
