On topic, not sure if it's changed because I haven't tried it in release yet...
In beta before PL 10 you could fully reset your points (so I've heard, I didn't try it until 11). After that you can only reset a certain ammount of points every 15 or 30 minutes or whatever. It could in theory take hours to reallocate the points you want for a melee to a mage class... unless they changed it like they talked about.
