You git what you git, and you don't have a fit. The 5-man instances we have in the game right now are all we're getting for the rest of the Mists expansion. But with new scenarios keeping things fresh, we'll have plenty of material to rescue us from instances or scenarios we've come to find an utter drag.
So let it all out: What's your least favorite Mists of Pandaria 5-man instance or scenario? Do the revisions of Scarlet Monastery or Scholomance rub you the wrong way? Is there something about a barrel full of monkeys that's less than a barrel full of monkeys to you?
