no, no, not what i meant.
just do normal northrend quests instead of the IQD daily ones, 30 minutes worth of it. (or whatever duration your IQD quests would take you).

You'll get about the same gold (counting rewards and DEs) but also get a bit of xp and shitloads of rested xp.
once you get all your toons to 70, some will actually be at 70.5, and they'll have 2.3 milion rested xp each
it would also be less repetitive i think.

just saying. i could be missing the point totally
