The main thing I remember in his reasoning is that fast travel was a good feature, that was in Daggerfall that was removed in Morrowind. That people blame Oblivion for "dumbing down" with a feature like fast travel

Fast travel was necessary for Daggerfall and Arena before it because the world maps were realistically sized for a nation and would have made the game near unplayable if you had to spend days real time walking to every destination. Morrowind had a smaller map, so no longer needed fast travel. Later games kept the small maps and added fast travel back in.

I believe also he says that in Daggerfall you had to specialize more and play as a class, and commit to it

Or you could just make a broken custom class.
