People are mixing two different aspects of the discussion.
- Should the game have more storylines involving Azeroth’s internal politics?
- Should the support of players for certain political decisions by the major characters influence the story.
On question one, I’d easily say yes. Huge mistake for WoW to pivot away from faction conflict and to turn to nothing more than “let’s confront this new existential threat and work together.” WoW has a serious drought of dramatic tension.
Players fought a lot whenever any faction had some victory over the other one, the forums from Vanilla onwards never ran out of posters wanting to fight over which faction was in the wrong in some part of the world and what they should do to each other. That was a good thing. It signaled actual investment in the plot.
You can get away with one good existential threat once in a while to unite over, but it only WORKS as a plot when players buy that the factions hate each other and would prefer to eliminate the other one and will probably be back at war. “This threat is so dire that even enemies must unite” is a classic formula for a reason. “This threat is dire, but everyone was already united,” works poorly, which is the current fuel for WoW.
On the second question, should player support drive the story outcomes? I think you could have an interesting system for that, but it would have to take account of various complexities that WoW would not realistically have the capacity to accomplish, so on that part I’d say no.
