I think this tickles me the most. People insist that this is some modern "woke" pivot but it doesn't even reconcile with that. It's rooted in regressive bubble era bullshit where everyone is treated as identical and there was zero celebration of any cultural differences that the modern zeitgeist wants, whether they succeed with it or not.
Whether the faction conflict is desired or not, the fact that you can't competently differentiate groups and actually constantly depict cultural differences is a total writing failure. There is a version of this setup of NPCs and this exact scene that isn't as homogenous. It is a deliberate choice of incompetent writers at this point.
They sometimes manage some element of cultural variance in each expansion zone proper, but they funnel it into new additions/races only and ignore everything else that's already been established.
