I hear the grind in EQ/EQ2 was terrible. My friends tried getting me into those MMOs, and when I hear them wax reminiscent about spending a day or two travelling to an instance plane or camping a mob for a rare weapon for days... what a time sink. I'm glad I never saw an appeal in them.
The grind in WoW isn't too bad and they keep making it easier and easier to level. Now the grind for money on the other hand... it's easier than it used to be, but still a time sink. I don't want to waste an hour or two of game time doing dailies when I could be levelling an alt or having fun doing an instance. This means I am almost always broke but that's something I've come to accept.
