1) best way to farm gold after max level?

2) I am doing hardcore and after I get bored I plan to quit, is selling IGG a good source of FG for hardcore WoW anni?

2) No harm trying to sell your gold after you quit for whatever the going rate is. People will probably feel safer buying from you if you aren't a big gold seller since those are the guys who get people banned.

depends on what class u are
like mages offering dungeon boosts earn a buttload of gold per hour, like on my server its 45g/5 runs for SM cath+armory runs
so 4 lowbies paying 45g each is like 180g per hour
