To begin with, I'm a recent 85 - I followed Dugi's gold guide, but my success has been relatively limited so far with enchanting (currently 525). I'm in a high population server (well over 40,000 items listed; sometimes more than double that), which has made making money hard with disenchanting. Often items are bought before you can finish scanning for them with auctioneer in the AH. The raiding scene though on this server is very good. Making money with enchanting (selling enchants) is also very hard - undercutting is very aggressive and there's probably no realistic way to achieve any dominance.
So I figured at least for now, I'm going to try to aim for tiny chest farming. I don't know how well I am doing though. Roughly how many chests should I be aiming for per hour? The video said 30 to 40, although I don't know what items Dugi has (ex: raid gear, just turned 85 greens, etc). It also probably varies by class. I imagine casters are at a distinct disadvantage - not durable like warriors nor do they have the pets that rangers have.
