nice video and thanks for taking time to make it, but again it's very server dependant. TradeSkillMaster is also not very accurate for AH prices, it calculates average prices but well, you know, on all servers some people are posting gems and stuff 4-5 or 6 times the real price, so in the end TSM says 30g for a gems but you will never sell them at this price. I prefer add ons like Auctionator tooltip that rely on lowest price.
On my server (and on most high populated servers) here is what you got:
-Hypnotic dust: 1,2g/U
-Greater celestial essence: 40g/U
-Inferno ruby: 75g/U
-Ocean Sapphire: 6g/U
-Ember topaz: 28g/U
-Dream emerald: 5g/U
-Amberjewel: 6g/U
-Demonseye: 25g/U
-Shadowspirit Diamond: 70g/U
Math again:
Red 75x52 = 3900
Blue 6x18 = 108
Yellow 6x24 = 144
Purple 25x64 = 1600
Green 5x28 = 140
Orange 28x72 = 2016
Meta 70x27 = 1890
Grand total on gems of 9798g
Now for the disenchanted stuff
Celestial essences 40x22 = 880
Dusts 186x1 = 186
Shards 70x4 = 280
Total on disenchants 1346g
Total earning 11144 - 5000 = aprox 6k
Special note for Meta gems: it tooks aaaaaaaaaaaaaages to sell them (yeah you don't need a meta every day compared to +40 intell gems or heavenly shards) so prices can go lower and lower. In fact, all gems are pretty hard to sell even +20intell/+20 haste or +20intell/+20spi (took my 2 weeks to sell 200 of these and i was undercutting people all the time, yeah that's stupid but i wanted to know how much time it will take to sell
6k profit but how much time to sell metas / dust / enchanting scrolls / gems (exept inferno ruby) ? days, nearly a week in fact and during this week tones of people will undercut you and no way to wait because there are tones of these at the AH (100+ metas, hundreds of dust and essence, etc...).
If you want a lot of gold everyday, you should go for JC+BS+Disenchanting on high populated server because there is a lot of bots = low ore prices (30g per obsidium/elementium stack).
Funny how easy it is to make gold on low servers, i'm 2 times gold capped on an overpopulated server, should have make 2 times more on that kind of server
Again it's a very nice guide but as all gold guide people are boosting prices and do stupid math (no consideration of time to sell and undercutting).
