For me it's Alexander normal mode.

I took a long break from FFXIV, and came back a few weeks ago. My LS/FC is pretty much dead, with mostly new members, and I can't find anyone to do Alex 5 to 8. I've been in Duty Finder for hours, nothing.
I tried my own Party Finder, no-one join...So I stuck because no-one wants to do this anymore.
