It looks like Truegold (Trugold?) is a daily cooldown.
And most high end recipes, of all professions, will use this material.
Initially, this will be the transmute for gold.

Shodakan suggested combining this with a Blacksmith to make your own equivalent Titansteel Weapons.

Down the road, when Jewelcrafting epic gems are introduced, they will likely have a cooldown to transmute.
Chances are, that will be a few months in.
Not sure which will be more profitable, but I'm sure we'll figure it out.



Initially, the new ores and herbs will sell for a massive amount.
A lot more demand, then supply.

Down the road, production skills (buying mats) will make more than gathering skills.
But you can make a ton on the initial demand for mats.
Definitely a consideration.
