I'm sick of the "random" dungeon finder

3) It seems to throw you into instances that your NEED achivements for. Has anyone considered that they get Occulas so much is becuase there are five achievements for that damn place, and most of you probably have zero of them? I get Azjol-Nerub a lot, and I have not completed the first boss achivement (watch him die).

It's an interesting idea, but my experience doesn't support that. I do a few daily heroics every day, have no Occulus achievements (including completing the dungeon), and have only gotten it twice.

Edit: Though thinking more about it ... maybe it does bias instances toward ones you lack achievements in, but doesn't favor them more heavily based on the number of achievements left to be done, i.e. Occulus is as likely to be on the "favored" list as any other with missing achievements. It's more likely to stay on that list, because it takes longer to knock out five achievements in a hard dungeon than two in an easy one. I only have about half the heroic achievements so if your idea is correct, it'd make sense that I'd get a more even distribution than some people are reporting -- I have a lot more "favored" instances on my list. Huh.
