Above is the definition of a grind and it has heavy derogatory overtones.
no, it is the truth. pulling the same mob over and over to kill it for hours on end is exactly that. standard bashing crafts for days on end making the same item is exactly that. they are both repetitive and non entertaining, but the only reason you do them is to gain sp/exp to gain ranks so you can do other things. they completely fit the definition you gave and it matches them both perfectly.
