This profile is optimised for tanks, but is also suitable for dps (I wouldn't recommend using it as-is if you're a healer). It's being released at the request of my YouTube subscribers.
The action bars and unit frames are hidden/mouseover when out of combat -- everything shows automatically when in an instance.
Also, for the transparent action bars and extra bling, check out "ElvUI Transparent AB" and "ElvUI Enhanced" respectively.
Enjoy!
