That's all really fascinating. But unless you have something that contributes to the thread, you probably want to shut up.
I've been gathering information about the best methods of gaining substancial ammounts of money quickly in TBC. In the last weeks I've compiled the whole thing and I must admit that when you look at the raw data, dailies come in way behind other means of harvesting gold.
For now the most profitable ways are related to the AH but requires a substancial ammount of knowledge, analyses and predictions. But farming is very close behind.
Some of the most profitable farming areas have excellent g/hr ratios. The limiting factor is that at some point (after days of farming there) you will see a diminishing return in profit because you cannot liquidate as fast as you are farming and stacking theses goods in huge quantities can be very risky.
So in order to truly maximize profit, one needs several farming points in order to vary his goods. After looking at several possibilities, I've found a zone that allows you to do so and did the test.
Result after 10 hours (2 hrs a night, 5 days a week, medium pop server)
Net gain of 3258g.
And an overstock that didn't sell during that weekend. With an estimated value of 520g.
Hence, in my book; intelligent farming bring much more than dailies and requires no capital investments (or Risks) unlike AH trade flipping.
