That could happen, yes; but the fact remains that they're likely to make it so that starting PCs are equal in relative power to starting PCs of the other game lines. This being a likely possibility, how can you begin play as a full Jedi Knight and still be on equal footing to that Smuggler/Pilot?
Because your character concept isn't necessarily going to be encapsulated by the mechanics at the beginning.
Your character concept can be "I'm a Jedi Knight". But you may need to grow into that mechanically. But the game should provide you with the basics of that concept at the beginning so you can still get the feel of it from the start.
