Though i haven't been playing long, I'm wondering what people do for decent amounts of AD?
Is it either just buy zen or farm high level dungeons?

Farm high level dungeons whilst abusing glitches/things that shouldn't work but do.

spider lair during dungeon delves has made me the most ad so far by getting lucky with t2 set chest pieces

doomguide made me very rich today. well over 2mill from selling greens and eggs. still have shit load of blues i dont want to unload.

glitches?

Dang, I'm trying to save up for a heavy inferno but that'll take forever xD

Need on all BoE Epics, sell Pvp gear (Although prices have dropped tremendously since a lot more people are doing it) or exploit Crafting bags.

crafting bags? whats that about?

Can't remember the quest name, but you do some quest over and over and get the bags that give Profession items.
