When it puts you in Leap of Faith by yourself

what's the point? Half the fun is standing around at the end and dancing while you watch the stream of other players falling down.

I'm guessing the previous instance was full, so when you queued it created a new instance and you just happened to be the only one there for the moment. Since Leap of Faith is not group-dependent content, there is no reason for it to make players wait for a "full party" or anything. If there's a spot, you go in. I bet if you'd waited around a bit more people would enter, but I dunno, this has never happened to me.

I once had this happen to me twice in a row.
It was kinda spooky, but also neat. Since I'm so small crowds can make this Gate rather... difficult.

I prefer getting it by myself. The sea of people jumping around is nauseating.

I would largely prefer à solo instance, less lagg and less idiots to mock you when you fall.
