I was looking at the credo tier map on the wiki and had a thought on how the credo quest and suicide problem could be solved. While I think that simply killing yourself to decrease the number of quests is ridiculous, I also agree that there are too many quests as they are now. The solution that I propose is to have the number of quests per credo determined by the number of requisite credos. For instance, the baseline number would be 2, for the hunter, fisherman and forager credos, then 4, then 6 and so on. That way, you could remove the suicide mechanic entirely.
Mathematically, the number of credo quests would be equal to 2+2n. Where n is equal to the number of requisite credos.
I get that a lot of people won't like this idea for a variety of reasons. I just wanted to put it out there as an option and see what ideas everyone else has.
