Doesn't this apply to everything in life? such as any other MMO/game out there, once you clear everything and its all been completed, there is NOTHING ELSE TO DO CAUSE YOU DID IT ALL. your demands are unreasonable, if they constantly add something new just to satisfy you, it'll never be enough for you, cause you will complete it and then complain that theres nothing to do.
tldr: You play too much, get some hobbies outside of swtor.
