Our last expansion was exclusively single player story-- no new group content whatsoever. Strange for an MMO? Yes, most of us agree it is. Basically, if you're looking for group content the community is not sick to death of, you should move on. You will be hard pressed for find a group of players excited about any of the current group content, and with no plans for future group content until late 2016, there might not be many players left once it does arrive.
It is not a very happy time for players who enjoy Raiding, PVP, GSF, or just about any other content you can't solo.
