Okay, so on one of my characters, I am Scryer. Getting exalted with these guys - easy mode, especially with the new dailies dropping sooo many marks, which I can hand in for rep. This of course also means that the price of these on the AH is very cheap. Arcane Tome, also cheap 9-11 gold. Because I was impatient, I just purchased all teh tomes I needed to get exalted.
Aldor - sigh, on the other hand, Fel Arm - go for 30-40g! And no one is stupid enough to trade mark for mark - given the price differences!
Why does Blizzard hate the Aldor. Perhaps there should be an NPC where you can trade in your signets for Aldor marks.
