Quest for Skills

So one of the big things in Prophecies, at least for me, was that you got to learn two skills as you did certain quests through the early part of the game. After about Yak's Bend, though, this kind of disappeared. I was wondering why that stopped.
On a somewhat related question, I was wondering what the decision making process was for which skills were chosen to be core skills and which were expansion-specific.
