Discussion of Main Scenario Roulette

[Thurmnmurmn]

It's optional. You don't have to do it you know.
If you make it so you can skip cutscenes when there's no sprouts, then you shouldn't get as large of bonus exp to do it. Then at that point why would anyone run these at all?? You'd fall in a situation where people would want sprouts for the bonus exp.
You said it yourself

If I have to do this as part of my roulette, I think the only reason I would do is because of its EXP bonus.

Overall though, the roulette is there to protect the MSQ. The only other duties that should be added are those with lots of story in it. And those don't exist past these as far as I remember.
