https://www.curseforge.com/wow/addons/research-viewer can list all different research trees for various expansions and i think we should log the talents a character owns and changes to that because quests in Legion and probably elsewhere depend on it.
https://warcraft.wiki.gg/wiki/Events#C_Garrison probably everything with TALENT is connected somehow, although i haven't seen one fire when research changes talents/order advancements.

The completion of a mission from the mission table can change the status of a quest , most of them hidden tracking for progress.
I have yet to sucessfully automate that instead of typing "/grail cb" once i received the loot :D
