Might also be that the faction war is easier to make relatable for many characters. Considering their character stories are probably full of conflict with the opposing faction. Funny enough Warcraft got a rich setting when it comes to past conflicts between races within the horde and races within the alliance. Where the baddie of the expac is not always something that you can make relate to your character.
Might also the fact that the big baddies this expac, atleast for 8.2, is not something the average character will be able to experince. Why? Because nazjatar is kind of like argus in the sense that it seems to be mostly only the champion and heroes going there. And by that it’s probably not common knowledge to everyone that Queen Azshara was scheming and heroes where fighting her.
Also blizzard having multiple story lines going on for BFA is zzzzzzzzzzzzzz
I’d be rather interested in getting to know why she thinks retaliating in an unprovoked war is ‘dumb’ - sure my character might be a fanatical frothing at the mouth Alliance fanatic but this war is hardly ‘dumb’ for the Alliance.
From her point of view the Horde just randomly decided to commit genocide. She isn’t the Speaker of Azeroth or a Champion. She doesn’t know the world is completely screwed, she doesn’t know about N’zoth, Azshara - so it’s a matter of retribution. The Orcs killed Draenor and now our world is dying? COINCIDENCE?
