You're right, Morrowind is a pretty good game but the combat system SUCKS. You have a random chance of hitting people with any weapon you use. Also, I really like the mudcrap and scamp (something that is not in Oblivion). Also, I'm disappointed that they took the levitate and mark and recall spells out of Oblivion. Finally, it was kind of disappointing to see spears and pretty much all of the different bow types get taken out of the game. Other than that, though, I really enjoy Oblivion (mostly because of the new combat system).
