Some of us are not perfect, nor are we OCD that we plan it all out in advance. I know there have been tons of times where I have hearthed back to dalaran, only to realize that I didnt get what I needed. Having 4 shaman helps for that, but I really dont enjoy playing them anymore. Anyone without a mage or shaman understands the pain of a 1 hour HS. I was using ghetto hearth extensively when I was leveling JC and BS. I'm glad they did it and will most likely get some use out of it.
