Firemaking, the laughs I had when I really started to grind this skill with the disappearing resource bug still in play as of 26/08/2013. You can light three rows of fires and go back to the first row and be sure every fire is out. With the DRB some of those fires may still be going until you log out/in. BUT, you don't have to log, as when you make another fire on a fire that was supposed to go out, you succeed. For all those mass firemaking grinders out there, burn baby burn.
