Join in progress should probably join a party in progress?

[Yasminou]

It has to do with the algorithm they use to match a player. For whatever reason the new system that shows how long the run has been going on is less helpful verse the old one that showed how many people are currently in progress.

The old display was not how many people were in the party, it was how many objectives in the duty were fulfilled (except 24-man raids where it was always 0/1). For instance a display of 1/3 meant 1 achieved goal over 3, i.e. in general, first boss killed.
