"Come over to the Dak Side. We have cake." Morality starts at 50. When choosing starting Morality, players can opt to spend some of their (base) starting XP to increase it above 50, or gain additional starting XP to lower it below 50. Either way, this is done on a 1:1 basis. I tend to award XP in a granular manner...+1-3 XP for significant narrative input, and between 18-20 XP per session. Also, taking from a suggestion in the forum archives, I break Conflict accrual into sets of 3...if the average accrual between players is 3 or less, then each player rolls a d5 instead of a d10, 4-6 rolls a d10, and 9+ rolls a d12. Thought I'd put this out there for general consideration. Sorry about format...limited net access.

IIRC you can get +21 / -21 morality at the start by making the selection instead of taking bonus xp / cash. Not sure what you are hoping to achieve.

In relation to the conflict roll, not sure why the change. In any session there should be morally ambiguous choices all over the show, and in general even the "paladin" should be getting 2-3 points. If you are finding Conflict accrual to be slow, then change when the morality roll is made. Perhaps make rolls at set points in the adventure, end of an act/chapter, or perhaps end of the adventure.

This assumes you don't have players who are happy or even keen to be evil. If someone wanted to play a darkside character they'd have a massive advantage over the other players. Early on in F&D design they considered somehting similar but concluded it was far better to have it cost XP to swing either way, rather than give you XP for playing dark side.
