This is a good example of a very small change that added really nothing (the grayed-out world didn't make it seem as if you were angry), but a beta is the perfect place to make that kind of experiment. I'm much happier that they tried it out there instead of on live. Now we all know it's terrible, bland and awful, and we can move on. To me, this is the beta working exactly as it is supposed to work. Had the change been awesome, yay new graphic. Since it wasn't, yay beta testers for getting it pulled. The system worked.
And yes, I hit several other cooldowns in that screenshot because the Enrage change was just that boring. It was just light gray over everything; it was as if I had pulled a stocking over my head.
It's open warfare between Alliance and Horde in Mists of Pandaria, World of Warcraft's next expansion. Jump into five new levels with new talents and class mechanics, try the new monk class, and create a pandaren character to ally with either Horde or Alliance.
