I love non-playable races. Most of the time I’m ok with side races not being made playable : lorewise, what matters is really just that they are actual members of the concerned faction, and as such are to play their part in war efforts.
The thing is, I find their status to be quite shady. They’re almost systematically recruited for a specific situation. The Horde needed the Hozen to strengthen their take on Pandaria. Same goes for the Shatterspear tribe, whose settlements in Darkshore were geographically interesting. Taunka were needed to fight the Scourge and for their knowledge of Northrend, etc. And then what ? Once those particular goals are reached, what is their status ? Do they ever participate in following worlwide conflicts ? Is their presence attested in further official faction stuff ? I know that there’s a Hozen Horde Vanguard in Dazar’alor, and Ogres serve as guards in several Horde outposts. Is that it ? I can’t think of a single Revantusk, Shatterspear, Taunka or even Hozen (Riko excepted) in Orgrimmar for example. (I’m voluntarily not mentioning the Unshackled : I never understood if they were official members of the Horde or just friendly temporary helpers)
I know nothing of Alliance lore but I guess the same goes for you. Do you ever see Alliance-marked Jinyu, Brokens, Furbolgs and Dryads outside of their respective expansions and territories ?
