This makes me sad. I work 2nd shift... 4pm-midnight. So I only get to group two evenings a week (not even weekend evenings), and one is for raiding. Other than that I try to catch groups Sat/Sun before work. So I can really see hearing oh we already did that are locked alot of the time or we just have two names left but we are gonna wait for ... who was with us before.
I do see the point about the smart loot, although it has never worked for me so far, so I don't see the issue. I personally thin I would much rather see the game be able to include more people and not have them be left out.
