From the choices, All of the above. I would love to be able to sit in a queue in order to finish X heroic on Coruscant, for example.
Not listed in the choices: Cross server. It's a pain trying to find a group at a server's offpeak time period. Even the Warzone group finder has trouble during off peak. In my opinion, Crossserver is the MOST important feature for a group finder so that we can find a group for Flashpoints using players from the entire community.
Love this. imo a really nice feature.
