The current system is not as effective as XI's system. It works, sure, but for a person that's looking for a party they have to keep checking over and over and over and over again. This is why people don't use it.
As far as looking for a party goes, "set it and forget it" should be the main approach, not search, search, search, wait 5 min, search again, "OK F**k it, I'll go solo/log off."
