I personally ignore the priority function entirely, dragging it out of sight and minimizing it. It's both annoying and useless. I mean it, completely useless - if you need an addon to tell you what to do with your own character, you just plain suck. But I'm using the "Aura buttons" feature, with a layout that allows me to see the status of all my dps abilities and cooldowns, neatly set up around my character so I never need to switch my eyes away from action.
