+1 for you then.

That would change mechanics and overall gameplay by 180 degrees, but i would really love to see that happen.

Throwing something fresh like that would negate "i-need-new-class" syndrom, which is happening mostly after overfeeding with current class. Ability to choose specialization is a good point i would actually like to see in official feedback.
Any chances it will reach SE? Or will give them a thought about expanding game mechanism at all?
