I liked the rarity and morale for a creature. There are so many things that a DM has to decide on and make rulings on that it is nice to have a system to help remove the burden of these two.
It was a good base assumption that you would be free to adjust for your campaign world. I don't really see any benefit from removing it and some people at least have lost some tangible benefit from them. For instance in Greyhawk how common are dryads? Is there at least a dryad in every forest, are there dozens or even hundreds in a larger forest? I don't have a clue. Of course as a DM I can make the answer be whatever I want it to be, but having a basis to make my decisions off of can help spawn more ideas. Maybe the MM says that dryads are rare, so it is rare to have more than a few dryads in a forest. If so, what is the reason for this forest having 30? It allows both the players and the DM to immerse themselves into the world more when there are these mysteries that they can explore.
As for morale, I sometimes have a hard time putting myself into monster's heads. Especially the bizzare or nonintelligent ones. When does a dire tiger decide that his meal is too much trouble? How about a dire boar? A morale system gives me an idea of how likely the tiger is to continue attacking despite resistance, probably less than the boar, but by how much? Just how cowardly are typical kobolds? Will they fight to the death to defend their own lives and the lives of their mates and offspring? Or are they apt to flee saving their own hides? A morale system allows the DM to choose to utilize it to make decisions for him if he is unsure or does not want to spend time figuring out how loyal basic guard kobolds are.
Another use for the morale system could be utilizing it with Diplomacy and Intimidate skills. The better the morale the less likely you will be able to sway them.
I am not crushed or impared by the absence of a morale system or rarity, but it is a tool that was taken away and forces the DM to come up with that on his own.
