I know some of you prefer to dispense with the roll altogether, but leaving that aside, do you have any alternate ways of triggering Morality via a roll?
The book says to see who's is closest to the d100 result, but that isn't really all that great because if the PCs all hover around roughly the same range, the "bookends" will consistently trigger their morality, and sometimes it'll just be whoever has the lowest score if all of the PCs get high on the scale.
One idea I had since it's a percentile, is to just determine what percent of the total morality score each PC possesses, then make a chart comparable to the Duty or Obligation system.
For simplicity's sake, liberal use of rounding makes the calculations simple, though it also means that Morality will not trigger every time. So if you've got a PC with 37, a PC with 52, and a PC with 78, that's 167. Round up to nearest hundred is 200, so PC #1 is 1-19, PC #2 is 20-45, and PC #3 is 46-84. Roll on the chart, and whichever range the result lands in is your result.
The drawback to this is that it heavily advantages PCs with high Morality, which doesn't make a ton of sense.
Another way to do it, I guess, would be to simply give each PC an equal value. So with 3, that's 1-33, 34-66, and 67-99. Then roll and see what comes up.
