Just did EV using the group finder, only took about half an hour to get one.
Five of them were in the same guild though so that helped speed things up a bit.
Got my 5 BH comms after so I'm good with that.
With my lower level alts it was a lot harder to find a group, I tried for a few hours to get one for hammer station but never got one. I don't think many players are using it yet, hopefully more people will start to use it.
