I get your point and I get why that wasn't the case. It was basically a means to an end to bring the Sue and Reed back. The villain was a big threat, but if she was utilized to her full potential then the book would have to keep upping the threats. And there isn't much higher than the universal embodiment of entropy.
I'm happier with issue 2 when I think of it more as a nice acknowledgement of all the past temporary members. I'd like to see Storm guest appear again, but by herself so that she has things to do and we get to see her interactions with the team.
