So far, the only planets I've really liked are Tatooine and Hoth, and Alderaan. Before playing this game, I had never heard of Taris, or Nar Shadda, or Belsavis, or any of those other planets.
The game exposes you to planets and lore that are mere sketched outlines in the movies. They expanded lore detail for you and you complain about it.
Conclusion: you want to play an MMO in the movie timeline. That's fine, but you know... they did not hide the fact that the lore was in a different timeline. You purchased it knowing this.
