In a campaign that I'm starting this weekend, I plan for the focus to be on the Je'daii that focused on a balance between the Light and Dark sides of the Force. Once the PCs start down the path to becoming the new Je'daii, I want to provide mechanical benefits to maintaining 40-60 Morality.
Some recommendations that I was given on Facebook included waiving the automatic conflict from certain talents, but the one that I am leaning most heavily towards was an alteration to the Morality scale:
1-10: +2 WT, -2 ST
11-20: +1 WT, -2 ST
21-25: Dark Side User
26-35: Unaffiliated
36-40: Balanced
41-45: +1 ST
46-55: +2 ST, Je'daii Bendu
56-60: +1 ST
61-65: Balanced
66-74: Unaffiliated
75-x: Light Side Paragon
x-x: -1 WT, +1 ST
x-100: -2 WT, +2 ST
The PCs wouldn't start out with the +2 ST, but they would need to set out on the path to become Je'daii.
