I used to use the AddOn OreCrusher a lot back in 4.0, however it seems that it is out of date for MoP. Is there any alternative available for MoP?
If you're not sure what OreCrusher is, it was an AddOn that would pull information from Auctionator etc. and showed you the best way to make money with your ore, whether it was selling raw ore or prospecting the ore and cutting gems. It even went as far as telling you if making them into enchanting mats was the best thing to do.
MoP ore is so pathetically cheap right now that there is no addon that will make it profitable. Unless you go back and farm some old world ore to sell it to other peoples alt as they level.
ore is so cheap right now it's too dam profitable to buy and do whatever with it (prospect/ smelt).
what I do these days Is prospect, make metas. craft blue, yellow and red superior quality gems. craft 450 ilvl necks and rings with serpent's eye. craft green quality rings/necks and disenchanted them, then make scrolls with the resulting mats. and eventually sell everything. a stack of ore costs 30g, and each returns roughly 60-70g after this process (even more if a certain guy on our server didn't crash meta gem market).
