More choice is almost always better. Blizzard desiging things in such a way that one player can havr a completelt different experience to another is ideal.
It’s also resource intensive on WoW’s scale…
Heck, it can be resource intensive on a small scale. I’ve been working on a quest mod for Morrowind that can be solved in like a dozen different ways with a ton of player choice and branching dialogue that the npcs “remember.” So many checks and variables to set and keep track of…
It’s worth it for the immersion though!
