Hiya since 2.3 there is a new island with alot of daily quest . Isle of qual danas!
Alot of people tend to ignore the mines there so if you ever done with doing dailys and feel like needing more money. Go follow this path around. Since this island ONLY has ( rich ) adamantite ore's you can profit alot.You also tend to find khorium somet imes . Even thou i played on a high population server ( ragnaros eu ) i could easily grind during peak times and in the morning / evening its even a higher chance of having al the mines to yourself. Just follow this path grind the ores / prospect and have a uber win.
