The problem is that since you have ground out every profession in the game, you are addicted to the next skill box. In the non-jedi professions, this is ok because you can obtain the next box fairly easily in one or two nights of casual gaming. With jedi, 800,000 XP can take awhile to obtain when you are getting 397 points per kill.
Unfortunately, you get bored of slaughtering stuff fairly quickly. Hopefully they will change things up in the revamp and make it actually fun to level a jedi character.
