The issue, to me, is that we're getting fed a lot of character exposition, but as far as single races go we haven't had anything significant since probably MoP.
One could argue the allied races questlines expand on existing relationship while being introduced, but there's really little room to work with if any at all. The most interesting in terms of overarching implications is the Mag'hars, and they eat a loss too.
Shifting the narrative from macro galactic philosophical concepts and focus on the who's who of single factions would help heaps.
