I'm curious if the Blizzard version will let you do the same, showing the icon when the "buff" is missing.

I use the Jesus face for my inverted slice and dice aura. Not having slice and dice up makes baby jesus cry.

But really, having timer bars is more useful - I want to know when SnD has 6 seconds left so I can plan to refresh it, a message/image popping up when it's already dropped off is too late. I only use power auras as reminders for things that I often forget (in a non-rested area with no poisons? There's an aura for that!)

Scherbaddie the way I have mine set up for my rogue is the 2 crossed swords right over my rogue with the timer above it that tells me exactly how long is left on SnD. Not having to look away from my character for base information like that is quite helpful actually.

Power Auras is an addon I use extensively on other classes, but at a minimum on my rogue. I use it for In Combat>no deadly poison on OH - given I apply them in order of MH then OH via a macro and wether its PVE combat or Muti/Prep PVP offspec, Deadly is the common posion to both. Obviously remaining poison time needs to be checked before a raid boss pull, but its nice to use an already installed addon to relieve the need for constantly watching on trash pulls.

I also love it for flashing up the ToTs icon when its off cooldown in combat, its great for training in the awareness to keep sucking up that delicious bit of 2*T10 energy!

I loooooove addons for streamlining my play and performance, but I try not to have too many as it gets tedious to keep them up to date and identify the cause when they conflict. I dropped a combo points addon and opted to use Power auras to create the same effect and add an audio cue. Hmm I think that might make me a Hyper efficency nut!

"with the timer above it that tells me exactly how long is left on SnD"

So, the same information a timer bar gives you but lacking the visual cue of a shrinking bar. Each to their own.
