ThePatriot,
So where has it been said that the ancient Je'daii Order actually does have the best understanding of the Force?
To quote from one of the creators of the Dawn of the Jedi comic book series...
" The Je'daii don't see a division of the light and dark side; instead, they believe a balance is necessary between the two. The Je'daii are like the Titans in Greek mythology who came before the gods. They are beings of great power and ability, but not all-knowing . They struggle with the idea of balance in the Force and know that being out of balance affects their power and the planet Tython itself. "
―John Ostrander
(taken from the Wookieepedia page about the Je'daii)
That a host of other material, including the actual films themselves, indicate that an idea of a "balanced" approach is pretty much wrong is further proof that the Je'daii Order didn't have all the answers.
If you want to believe that as your own personal canon for your games, that's one thing. But there's nothing outside of the Dawn of the Jedi comic book series to support that idea as being applicable to the larger canon. As MaxKilljoy cited, the Je'daii Order is the most non-canon of Legends material, and has only gotten a name drop as being older name for the Jedi Order that most galactic sentients are aware of.
I already gave canon sources. Start with The Clone Wars Mortis Trilogy and Yoda's Journey in Season 6.
EDIT: You're jumping into the middle of a discussion and you actually proved my point that the only thing that screams Jedi in F&D is the morality mechanics. F&D fails to address other Force traditions adequately.
