There are plenty of people in the GFFA that got along just fine without being Force-users, and there plenty of Star Wars fans who are far more into the pilots, scoundrels, and bounty hunters of the universe than the stuffy old Jedi.
I'm very excited about this, because I really love the Old Republic Era of Star Wars, and this one is taking place about 3500 BBY, which means it's a relatively unexplored era of the Star Wars timeline, giving them a lot more breathing room in terms of story and design. That means they have plenty of leeway to make non-Jedi classes compelling.
