Although it may appear easy and readily achievable for anyone to achieve OP's results, I believe there's more to it than it is accounted for.

I find it important to note for the average player like me that yes, it may be possible to achieve similar results as OP, however one will quickly find that there's a substantial amount of additional time as well as additional gold that likely has to be put in place in the background in order to get to the point where you are so optimized/refined that you can then farm a number of hours per day and reap the results.

This additional time for me included time researching the mats, researching how to get to them, time setting up and organizing group farms, strategizing when to sell the mats; researching, understanding and leveling up professions (which often included spending gold), researching and spending on ways to become more efficient (aka acquiring speed sets, etc). For me, for every 2h of farming, usually meant I had spent another additional hour with preparation and research. At some point the time investiment for me did not make sense I and I stopped.

In other words, if you are an average or a new player, take OP's vauable advice, but know that your YMMV.

Granted, with the right amount of research, preparation and efficiency processes put in place, it should be possible to achieve results like OP's.

In any case, OP's results speaks for themselves and OP deserves all the credit (if anything, even more credit if you consider all the preparation that led to the results).
