first off try to get a touch to professionbuddy... u need practice with it , is a wonderful tool ... then make yourself an excel file with data from wowhead on which percentages are the gem drops from prospecting and you will be able to calculate the profit based on everyday AH prices, i had similar back in Cata, and i had 3 of these, one for selling cut on AH , one for selling uncut on AH and one for vendor, all based on investment, if stack was 20 g i could sell straight to vendor apart from reds, if was more than 20 i could only do it thru AH. if u farm yourself the matts then u can do whatever you want even vendor bars or i dunno, but thats not something that gives you good profit /hour .... and ofc risk you to get banned since u use bot longer periods. cheers
