This. Power Auras is almost a required add-on these days. Yes, you can get similar functionality from various buff mods (like Elkano Buff Bars, which is nice and I also recommend for replacing your buff bars) or various SCT add-ons, but I find that visual cues are not only easier to notice, but much more intuitive. I have it set up to put a glowing yellow aura on top of my character (intuitively like I've got the proc), and even when I'm not looking directly at my toon, I can see that it's procced and plan how to use it. Virtually any other add-on would require reading text, which I can't necessarily do with my peripheral vison, and adds just the tiniest bit more brain lag.Originally Posted by Danner
I also find it useful for watching other procs, like I have another aura set up for watching my serendipity stacks and I have it change color based on how many stacks I have so, again, I know at a glance exactly where I that stands and I can more easily plan out either how I'm going to get more stacks or how I can best use it.
Finally, it's fantastic for watching for encounter specific mechanics. I have it warn me for stacks of Biting Cold on Hodir, or stacks of Saronite Vapor or Mark of the Faceless on Vezax, or if my Sanity gets too low on Yogg, etc.
