You're right, I wouldn't use it at all. Then why should they spend time and resources on making a system that will ultimately be a failure for 90% of the people who use it and discourage those same people from using it again? As cool as an in-game destiny LFG would be that would allow us to pick and choose our groups, the amount of coding that would need to go into such a feature is a lot. We probably wouldn't see something like that until Destiny 2, if not Destiny 3.
