I've know this for a while and never seen it posted before. I also searched a bit and didn't see any threads on it so here ya go.
While your on a transport such as a Zepplin or Boat that makes regular trips between continents, right before you hit the loading screen, Life Tap untill u cant anymore, then right when your out of the loading screen use Hellfire untill u die.
When done u will res at the next citys Graveyard with no Dura loss. Ive used this from patch 2.0.10 and it still works. Its a great way to save that little amount of time if your in a big rush.
Thats it, Good Luck and Have Fun.
