I said it when they began doing it in WoD, and it remains relevant and a source of problems to the game right now:
Making the player character an actual story character and affects things was a terrible decision since the game wasn't built that way from the beginning. #Warcraft
I've always played World of Warcraft for the actual characters they made in Warcraft 3 and in each expansion not for my own character. I like the little cutscenes of us in it but not us doing something like going toe-to-toe with an Old God on our own.
