Cost

We all missed having to pay to respec, right?

Let's assume you have a ton of gold. Let's say you stroll by the auction house and you see that the WoW Token has dropped to around 20,000 gold (in the US it often is below this, in the EU not as of yet) and you decide hey, I've got a ton of gold, I'll buy a year's worth of tokens and so you do. You dump 240,000 gold at the AH, redeem a bunch of tokens and bam, you're paid up for a year. You just saved fifteen dollars a month (again, using US numbers, I know it's different elsewhere in the world) for a whole year, and you're feeling pretty good about it. And there's no reason you shouldn't - that's why the token exists, after all. What I find interesting is to consider all the side ramifications of this deal.
