shitting on methods that legit players enjoy and use to get gold in a blizzlike manor just to stop gold selling is stupid. i know many people who play certain classes or play just to farm certain things because its their favorite thing to do in vanilla.
get better at catching gold sellers, dont stop gold farming techniques because of them... if leaving these methods up so gold sellers can farm gold easily and eventually "ruin the economy" is letting them win then surely ruining certain aspects of the game for real players is letting them win even more.
