IMHO, if you're starting a game at 0 earned XP and using the default campaign setting, you should gently discourage players from taking a lightsaber spec as their starting spec. While an important part of the system, these specs do not really facilitate the creation of deep or interesting PCs from the start.
While I agree that the lightsaber form specializations themselves don't lend much to the 'fluffy depth' of a staring PC, I think that the combination of the career and skill selection at character creation can suitably carry the load, i.e. I think a Jedi character can be made interesting based solely on career and skill choices.
Emphasis mine, and I agree. Perhaps my head is still too stuck in the beta book days -- the revealed fluff in the CRB and BBox starts PCs significantly farther down the road of becoming Jedi than my initial interpretation. I'll admit I'm biased towards seeing what characters where like before they became priests...
