well, i personally haven't made it that far yet while beta testing. They've been limited in what they've released, and sense we're supposed to be testing, they're asking us to run through as much as the content as possible. So far the pve has been enjoyable. I haven't gotten to the point where i can be a klingon yet, but i'll let you know once i get there.
the only thing that frustrates me is that they haven't released information on pricing plans yet. Supposedly they were going to release something today, but that has yet to happen. I've decided not to drop any money on a pre-order until i know exactly what it's going to cost me in the long run.
