I kind of feel like once you get to a certain point, adding a few more minifigs doesn't make much difference. I have about 90 Uruks and while I wouldn't complain about having more, I'm not actively trying to get them. Any MOC that I would want to make that needs 100, can do just fine with 90. My current goal is to get a combined 100 minifigs between all of the orc and goblin variations. At the current distribution levels, it just seems impractical to try to get a large quantity of any one type.
