I have found this game is slower than most at Launch. Star Trek Online took me a week to max level, and nothing left to do. The arc from 1-50 was the same for all types of characters as well, so I dropped that game.
I have reached level 24 since I started a week ago, and I play way too much (ask my wife). I might hit 50 in the trial period, but then I am going to fire up the next storyline, and the next, and the next, until I have done them all.
