Some things I wonder why.

Q: Can I resell a WoW Token after I’ve purchased it for gold?
A: No, each WoW Token can only be sold once. After you purchase a Token for gold, it becomes Soulbound. At that point, it can only be redeemed for game time.
Q: I need gold! How do I sell a WoW Token to another player?
A: You’ll be able to sell WoW Tokens through a dedicated Token exchange in the Auction House, located in a new Game Time section. WoW Tokens cannot be traded or sold any other way.

In Rift (they call it REX not tokens), three things I do are stock up on REX when they are cheap in AH, trade them to my alts when needed, or relist them in AH if prices go way up.

I wonder why they just couldn't make tokens a regular item to be bought and sold for whatever reason I want?
