Given the current leveling design, you’re correct in stating lore status does not have to impact questing and there are opportunities abound. I’m not denying that. We can Chromie to any expansion to do our questing all the same. So mechanically there technically is not a need to allow for ‘fair’ questing. However, the base/core continents are at this point in a state of Cataclysm and have been for 10 years. Im working off the presumption that these developments would replace that experienced world, go beyond story advancement with nothing to show for it. I feel as if this has been the presumption of this entire thread. To update and experience the world in conjunction with the story.
However, if we are updating the world with content then what is there to do for the Horde players specifically in Nothern Kalimdor? Do we just take seven zones away from them as players? Beyond narrative advancement a lot of us would like to right the wrongs of development from Classic, which is what Cata attempted to do. Successfully or not is a different argument. Pretty clear I don’t think it did, giving us exclusive but not faction zones like Hillsbrad, Duskwood, Redridge, and Wetlands. Even took away half of the Barrens from the Horde to provide Alliance narrative and questing. Im not suggesting or even requesting that there be a Horde presence in these zones, but to at least allow the stories to be available. Why remove 1/3 of a continents content for one faction?
But you raise a question about neutral or 3rd party organizations. What is their role in Azeroth’s politics? Do they have a duty to defend particular lands or to intervene? Sure there are individuals on both sides who’s allegiance is to their faction/people before the order and may leave when push comes to shove but on an organizational scale, what is their role? I’d argue that they remain neutral. Wary perhaps, and that can be the a point of development.
You make the argument that it took Derrek for Baine to do something, but Baine is not the Horde Arch-Druid in the organization. Hammul is, and Hamuul did nothing for the war, instead staying in Sillithus and trying to heal the world. That is who you make the argument for. What Malfurion, thankfully, didn’t do is pull a Jaina and take the whole Cenarian Circle against the Horde like the Kirin Tor. There is still room in the organization for it to be a force of cooperation.
