The gold accumulation is just another game within the game.
Just because there's nothing I can buy that I want; could buy some PvE upgrades, and do a Heroic team I suppose, but have no interest in the PvE aspect at the moment...
Doesn't mean I don't want to see how far the gold game can be pushed; and next expansion there might be another 200k (across a team) sink like Vial of the Sands.



Looking at the numbers...
Transmute Life (at 8g per, on average).

30 Life (240g) = 10 Fire, 10 Water, 10 Air
Plus 3 Pyrium = (20g each) = 60g
Total cost in mats per Truegold 300g.

30 Life (240g) = 30 Air
Total cost in mats = 240g per 30 Air.

Truegold was selling for 800g per bar a couple months back.
Last month it was in the 700-750g range.
Today, it is barely over 400g per bar.
So Truegold is 100g profit per bar.
Transmute procs are nice, but that's an average of +15%

30 Volatile Air sell for 16g each, when sold as singles.
Which is 480g per 30, or 240g profit per 30.
Quite a bit more than Truegold.
Stacks of 10's, at 219g 99s 99c, sell very well... which is another 180g profit.
Plus the same long-term 15% additional Volatiles of random types.

Back to Air.
Thanks for the input; don't think its worth trying to reset the price on Truegold.
