Dark Side Mastery
Like I said I would, I have found that when you max out the Dark Side, you get a power boost. I've only got this with Jedi Sentinel and Sith Lord, so I can only give you those stat increases: Sentinel gets a +3 to DEX, and Sith Lord gets +50 Force Points. With this new information, I'm not sure my last hint was entirely accurate--the one mentioning "Light Side Mastery," if it did indeed get accepted (too lazy to look right now... ;) )
Anyway, now you know.
