My druid has the most keybinds of any of my toons, and coming back to MoP after a long break, I had to unbind everything, write it down, assign priority, and map it out. The screenshot below is what i came up with. There's also a side bar that's mouse-over only with improved form-shifting macros, and a few other things I don't need to see all the time.
**EDIT: I remember grabbing this screenshot earlier today because of the back-and-forth about feral PvP damage being low. I wasn't exactly stacking KB's in this particular BG, but being outdamaged only by a spriest, mage, and DK made me kinda happy :)
