We have confirmation in an upcoming dual spec ability.  Meaning we can have 2 specs to switch between.  At the same time the developers stated they will be addressing the specing UI to give ability to make sure you do not spend points without a confirmation.

Not only is auto shot for a hunter fixed and will not be clipped by another ability, but not for priests, mages and locks wanding is the same.  It will stop as soon as you cast. No more having to wait for the cool down to heal or nuke.  Yea!

The UI panel is over. Looks like a few cool things coming.  More notes to come as the class discussion will start shortly.
