I will say this: I've run more PUGs in epic levels during Crystal Cove than I have when it wasn't around. And I'm not talking about Cove runs either.

It is like the PUG scene is being turned on its head. I remember distinctly (maybe a couple of years ago) I had a terrible time getting PUGs going, or getting into one while Marbar and CC were running. Now...I have no problem.

I think this might prove that "contraction" theory.
