I quest bot from 1-80 and then use archaeology buddy from 80-85. You sacrifice on the reputations from the cata zones, but with mists around the corner, it doesn't matter. Arch is safer and you do make some awesome money on it by selling the grays and whites you make.
I think when my warlock was done at 85, he had like 3-4k gold simply from archaeology. I used that money to buy 280% flying on my next character once he hit 80. It goes pretty fast and it's nearly 100% AFKable. I just get stuck in the giant trees near the dragon shrines in duskwood and hinterlands. Blacklist the twilight highlands digsites and you'll probably never die unless you get ganked. The fire elemental mobs there have an AOE ability that the bot will not move out of and you'll die from it very quickly.
