For me personally, balance power tracker was my go to because it shows the change on the power bar once a cast is started. "Predictive" energy cycling if you will. The default bar doesnt show the resulting energy change until a cast is finished which is too late if you wanna know what spell to que next. Though with the bar automatically cycling in WoD and spells not generating energy that'll be totally moot. I just hope an addon that makes it look like balance power tracker pops up cause the default one is terrible. But ya if all you wanna do is move it, moveanything will always work.
