Advanced Class Respec
A big discussion on the official forums is whether we should be able to change our advanced class. BioWare is likening each advanced class to a separate class rather than a different spec compared to other MMOs like WoW, so it would be a much bigger change than something like a warrior in WoW respeccing from arms to prot. Do you think players should be able to change their advanced class?
I think it would be a pointless restriction to not allow changing your advanced class, but I could see them taking that route. It makes players roll more characters thus keeping them playing longer. I could see it being removed a while after release though.
Just a note that you will be able to change your skill points in your advanced class, so your build definitely won't be permanent.
