The cost is pretty steep, and it's eating the whole weekend cause I'm not commuting home.
I've been playing this game for almost two years and pretty much bogged in C class. I will probably use what I learn from the class to evaluate whether I actually have the drive and ability to go further or if I should pick another hobby.
Other classes pop up from time to time, I think Ben B is planning to offer them pretty regular. I've seen Chris Tilley offer them on occasion. There are others none of them seem particularly well advertised, but if they fill why would they be.
