I think there are too many quests that only involves going to nordic ruins and killing everything. At the beginning it was cool to go to nordic ruins. After the 10th it started to become a bit boring. One thing I like in morrowind was that not all quests in the guilds involved going to caves, castles, ruins, etc. Some were just about convincing some guys to join the guild or kill them if they weren't convinced. You might be thinking "But that doesn't envolve enough blood!". Yeah but it is still better than trivializing every ruin in the game.
Also, the items. For me the biggest disappointment in the game was the 9th dragon priest mask. And there aren't enough unique and good items. It seems that the best items in the game are those you create with your smithing and enchanting skill which ruins even more your motivation to go to dungeons
