Um, WoW’s literal history of game expansions and patch tests would disagree with you.
Blizzard has only once chosen to partially alter a quest chain ever.
Mists of Pandaria and Varian becoming the High King of the Alliance.
They literally changed it to Tyrande, a 10,000+ year combat veteran, charging directly at an enemy fortified position, because Varian was getting raked over the coals story wise.
Gee, it’s like the narrative angle of, “The Hero’s Journey,” might require some coal raking level story development to feel like he would be safely invested as said story in game required for him to become the Alliance’s High King.
That is the one and only single story patch change I am aware of in WoW’s history.
If the Community Council and the secret forum are anything like Blizzard’s “listening” to player feedback from the PTR during patch and expansion PTR builds?
WoW and we are doomed.
