Mitigate the Oculus LFD deserter debuff?

My alt is now at the stage where the most frequent LFD heroic I get is Oculus. I naturally drop group immediately upon arrival.

The deserter debuff is 30 minutes? Is that clock time or game time? The best I can do is just keep the account logged in on a second copy of WoW on my desktop or on the laptop?

Any idea what gear range pushes you towards Oculus? Leaving gear in the bank would not help correct? Until you get to the Icecrown heroics, there is nothing one would want from a heroic other than badges.
So I would be fine with just D/E some gear and replacing it with blues or greens. Run 50 or so heroics with the blues then get 4T10, wand, etc and some 264 crafted pieces the same day.

Any suggestions on minimizing the problems caused by the Oculus deserter debuf?
