So are the token costs going to change upon release?

Because after a good 5 hours of playing, I've managed to rack up about 800 out of the 9,800 that a single class requires. Granted I am stilling getting the feel for the game, but I am only about 8.16% of the way to unlocking a single class, and about 0.74% of the way to unlocking them all.

I understand the concept of incentivising cash purchases, but why even dangle that so far over head for the FTPers? I pretty much just see myself getting MAYBE one class if I can manage to not get bored of the 2 Medium starters before then.
