Have the devs said anything about fixing the party finder?

I have friends that are considering quitting because they can never find groups for things.

It's very clear the party finder is not showing you all the parties, it seems it pick a random batch to show you from all available parties. You can have 2 people open party finder at the same time for the same dungeon and get entirely different party lists. So the reality is that there are people making parties and running content, the game is simply not telling you about most of them for some god awful reason.
