If you right click on your minimap PvP symbol that handles BG queueing when you're in WG, simply click the "Leave Wintergrasp" option you're given and it'll operate functionally identical to a ghetto hearth. Very useful for getting back to dal when you're trapped in WG or Sholazar or wherever with your hearth down--just fly over WG, right click it, and ghetto hearth. It still puts your hearth on cooldown but can be used with it already on cooldown. I found it very useful for doing my dailies, especially the WG and fishing ones.
