Just a quick update from my end, after contacting all my 14 suppliers, including ones I am personal friend's with over the years, gold is hitting near rock bottom, the worst prices in history.
Every server is going below 0.5, my $1.2/k servers from a few months ago have hit $0.4/k, this is EU and US.
4 US - $0.4/k - $0.5/k
6 EU - $0.3/k - $0.4/k
Out of 14 responses from resellers they all said the same thing.
"Too many bots on the market farming gold, we can't sell fast enough"
My private buyers have demanded that I sell to them much lower, as in $0.9/k as they can get gold much cheaper from the chinese, even my most loyal private customers are demanding I lower my price.
Mat prices are falling, it is getting harder and harder to make gold from gathering, nobody want's to buy and every auction on every server is overflowing with mat's anyway.
You can get to 20+ bot's and start get a good amount of cash, however, you WILL get all your account's linked up and a lot, if not all account's will be banned at the same time, leaving you back at square one.
Majority of people know most secret's, to selling, to getting the most gold, to method's of whole process, put on a paper and way to easy now, follow a few guides and you're in there, resellers are pretty easy to find now and are not hidden.
Combine all this and It's suicide, I am learning another MMO as already stated in my previous post and would suggest everyone to do the same, this market is WAYYY over saturated and has been for a while.
Goodluck to everyone, hopefully it may pick up but I sort of doubt it with the lack of cata content and the incredible surge of newcomers trying to make a buck or two, the golden days are long, long gone.
