I have to admit, I prefer to work for something, than to have it randomly drop by chance, into my bags. The sense of achievement has gone for completing an instance....
I often wonder, is it needed for small group instances, and landscape mobs, for a char to have the most powerful equipment? Is that not why it was included, mostly in raids initialy? Seems to me, that its raid instances, that need a char to be really well equiped, to enable the completion of the raid. Of course, I may be wrong...
