This. I had a blast playing with my Sage. I was addicted. I started 20th of December, and reached 50 about 2 hours before the year 2012.
Excited that i had access to all of the endgame content, i couldn't wait to play more. After a few days of playing battlegrounds and trying flashpoints, it hit me. There really is nothing to do, the best part of this game was the journey to 50. Propably because of the new-factor. Everything was new and exciting. Reaching level 50 killed this game for me.
I know i won't be coming back. I love Star Wars, and i sincerely hope they will make a game worthy of the saga sooner than later.
Goodbye, may the force be with you.
