Two major suggestions for Credos rework:
1. Quests should be more generic. Instead of "Pick a parasol mushroom", "Harvest 40 carrots" , "Craft 4 wool shirts", they should have larger numbers for generic items: "Pick 20 mushrooms [any kind]", "Harvest 100 tubers", "Craft 10 shirts". At least for Tier 1-2 credos, possibly Tier 3 as well.
2. Instead of picking a Credo at a time, potentially having all of them on one character, make it a "either or" choice by making us choose the last one. For example, I choose Blacksmith, and I'll have to do all its required credos, but nothing else after that. I can't be a Blacksmith and Tailor at the same time, as they are not on the same branch. The credos tree would need rework, obviously.
