i was just wondering how everyone has been making their gold since cata was released. i have both mining and herb so i farm deepholme in 3 circles (1 around the middle, 1 around the outside of the middle and 1 around the outer areas of the map.) it takes about 20-30mins each time im finished with flying through once (depends on if you slow down and try and find every last bit you can.) with this the out come is around i say 2k-3k an hour depending on how many others are flying around the same time as well.
i also found that delicate wings are a nice way to get some money (a stack goes for around 1k on my server last i checked.) i think i was able to get about 2 stacks in an hour or so but i was also stopping at points for a while.
