It would be awesome to have a Combat Metrics plug-in or Add-on that kept track of your uptime percent on skills that have durations. As a NB, I would like to see my uptime on things like Crippling Grasp, Wall of Elements, Merciless Resolve, etc. I am trying to improve my rotation, and having this tool would be great for gauging progress and identifying problem areas. I already use a buff timer which puts a count down on the skill icon, but having both would allow me to see if I am truly improving those up times.
So, to all of you Add On authors out there, would this be doable?
