Is there a chance you can make a guide step by step? Put the quests in the order you'll come across them and maybe include side quest / character quests recommendations between main story quests to hopefully complete everything. I think maybe including level recommendations would be really useful as well. 
I know a guide probably isn't at the top of your to-do list, just thought it would be really helpful for us completion-ists as there is a lot of content and replaying the whole game for certain missed things / events is a lot heh.
Thanks!
