My biggest problem with the OP is not his understanding of how the content finder would possibly work, but rather the fact that newbs or bad players should not be allowed to play with experienced players for an AV run, because they don't know how to run it correctly. How else are players supposed to get experienced in AV runs if they don't take the opportunity to run it with more experienced players, or at the very least - trial and error a new dungeon when it's released.

Everybody is a newb at some point in the process, some players are just slower at getting access to things.
