I thought that in killing hundreds or thousands of foes there was an effort and the looting was marginal as compared to the effort needed to kill....Heaven forbid you should have to put in at least a little effort. You're talking about all but setting the game on auto.
Personally, if the monster is one that I am expecting to have good loot, then I enjoy the opening up the corpse and checking out the loot, but when I know that 99.99% of the time it is junk, I personally find it only annoying to have to open up the corpse, check loot which I know before hand is almost inevitably junk and waste time in the effort...... So, I find enjoyment in manually looting, but only when there is at least some marginal thrill (i.e. a decent chance at good items), with low spawn, this unfortunately is not the case for too much often...
