Being bored and trying to find a way to make the game more fun I have decided to challenge myself. Play the game with no UI at all. The typical keybinding to turn off the UI is alt-z. After playing like this for a few hours I have noticed more things going on around me than ever before and am largely more aware of everything around me and because largely familiar with the rotation (shadow priest). So now I challenge other players to try playing the game with the UI turned off and see how it fairs for them.
P.S. I was able to do 50k dps at 481 ilvl with gear forged for holy and follow fight mechanics in raidfinder so far without using the UI.
