Retail multiboxing Gold farming

[balton]

Guys, in the last few days I noticed a decrease in my sales of minerals and herbs and the prices of these items also decreased in AH (I imagine that the competition has increased). I am looking for other ways to earn gold. do you indicate some form of farm raw gold that is not raids or dungeons? perhaps some point of suramar with great respawn of mobs to gain cloth, greens and trashs that will be sold later. any tips?

Obs: i play with 4 accounts
