It's there because otherwise people will almost certainly find at least one build for one class that can abuse in-combat skill swapping so badly that it makes up for the loss of NV.
Anyone who doesn't think this is the truth is really, really, really fooling themselves, especially for grinding XP, since Monster Power gives a far larger chunk of bonus XP than NV does. People are already ignoring NV for certain XP grinds. Without this CD, those people would be able to change skills on-the-fly with further impunity. The same goes for Demonic Essence farming or any other farming that isn't based on NV.

Why would they change it?
What would this offer the players? How would this make the game better?
