Level a guild with pimpmyguild and super invite... Sell it. Takes time, and a lvl 25 guild on my realm is about 20-30k
Use zuabros glorious set farm, each breastplate cost 10-15k , you can farm 3-4 in one night if ure lucky, you can farm full set and sell it for 100k ... <-- i wanna migrate to your realm, all the pieces sells for a max. 2500 ea.
Grind instances, gph is lowest but you have chance to take expensive shit like rares, funny trinkets, transmog, mounts... <-- Botanist's solstice is highly recommended!
Rogue pickpocket.. <--- The GPH gain depends ALOT on you being the only rogue there, if there are 1-2 other rogues, your gph is down to like 300-500 gph.
AHbot to scan and buy cheap greens, some noobs sells 50-70 greens for 10-50g you can resell it at 5k because are transmog demand items <-- Your realm is amazing.
Skyshards farm lol, really good profit <-- Alani kills sells for 20k on my realm
This is the final line of MoP, proffesions profits are really low, like in all exps at the end, so if youre following to try make huge amount of G with this methods, sorry, but you dont know nothing about game economy. This post is useless right now, in my opinion
