Agree 100%, there are a few MMOs that have developed some pretty decent LFG options. The best i have seen, allows you to queue for a "Zone" and either select a "fastest group possible" or "balanced group" with traditional tank, healer, dps classes. I wouldnt be surprised if this was in development right now, although it should have been implemented by launch, especially considering this social points thing they have going..
Hopefully we hear something soon.
