What's frustrating is getting a place like Sastasha when clearly your group is all synced down and could have gotten something higher, like Haukke or otherwise. I think what they do is it checks what is queued, readies a dungeon on a first come first serve basis, readies the dungeon they could have gotten, but then someone (level 15 or so) leaves queue. Well, the dungeon is ready anyway, so someone else replaces that one who left queue. My theory, anyway.
