1. Horse riding. (I have to assume this was just plain laziness, seeing as oblivion had both first and third person view for this.)
2. Sitting. (At least they bothered to get the view height correct this time around.)
3. Finishers. (Should be very easy to fix, seeing as they have both first and third person finishers for each type. Why they decided it should be random is beyond me, and just foolish.)
Can't seem to think of any others currently, but I know there are some. Some of these should be easy fixes, some perhaps impossible short of a script extender. I don't expect these to be fixed pre-CK obviously, just letting others know this would be appreciated for both immersion and just plain common sense gameplay that should have launched this way.
