Is in new things added to the game. I:E - BOE's, Mounts, anything recently added.
Im not talking about getting 20g profit margins. Im talking about 1k+ profit margins. Cutting gems, Doing enchants, Mining, Herbing, Truegold transmutes, Flasks, All have decreasing profit margins and its going down in a hurry. Many of you have noticed that in some cases, Its a loss. Guild's are doing their own flasks, gems, and enchants. With more guilds around, Its obvious the market for each has all but crashed.
The only way to make serious amounts of gold is to prepare for new additions. Such as saving pyrite for prospecting future epic gems as well as saving your Tokens to buy patterns. Sure, It could backfire and token count is reset or a new ore is introduced but the potential for gold is just too much to ignore. I estimate 30-40k I will receive if this plan works. More recently, New enchants and meta's were added. The cuts go for 500g+ and you can make quite a bit of them. Soon they too will decrease as others get the plans but for now its a goldmine.
BOE's. People are paying a good amount to skip normal dungeons at 85 and get into heroics asap. With BSing and Tailoring, Im making 20k a week via this method. Mounts as well (Vial of the sands). I know a person who got the recipe for that dragon within the first week of cata. He is now at gold cap on 5 toons.
Just my $0.02 . Gogo discussion.
