Go learn how to play with AH... and don't be a slave/worker collecting gold from dungeons/raids. There are quite a number of AH guides out there.

Personally I feel that gold is overrated, like some ppl will boast to you how much they make per week or if they have 4M gold cap etc... I've raided and completed all cutting edge achievements since t9 and have not had more than 100k gold at any one time.

So I dunno why more casual players need that much of gold...
