If the reward is necessary, but the enjoyment low, its a job. If the time investment is low, then the reward loses much of its perceived value. If the (subjective) balance between the three factors is a positive, you basically have a hobby.
Good grinds are usually balanced in a way where rewards are great, enjoyment of the process is somewhere in the positive side (usually just barely), and the time investment is high.
Its much like how people don't like easy raids. There is no sense of achievement, just free rewards. Its just taxing in a different way.
For an MMO its kind of important to insert time fillers like this, as they cannot provide enough content to maintain a stable subscriber population in the long term otherwise.
Example: I paint Warhammer 40K figures. I hate painting. I'm not doing it for the fun of the process, but the extreme satisfaction when I finish, and they turn out great.
