There are easy ways to grind gold, you just have to be prepared to spend a few hours in low-level dungeons.
Sunken temple for instance - You can walk through there, clear everything and come out with 2 mill from the items that drop (use 9k scrolls on uni's) - often you will get a book you can sell on AH as well.
That said, you should be able to grind more gold from higher-level areas, but that isnt the case since the prices changed in the last update... which kinda sucks.
Hmmm...thats a good point about noob areas.
Gotta admit I had thought (and hoped!) the days of going to noob areas was over for me.
Not sure how I feel about it, maybe 1 step forward, 15 steps back sums it up...
