For the time being, I was thinking of limiting involvement to just the alliance.
Strictly because their presence seems more welcome and involved than the Horde.
Rather there is quite a bit of Human involvement but little from other races. The Forsaken would be the first of many pauses and concerns, for valid reasons of course.
Anyone would be cautious around the undead, although that stigma was different within the Priory of the Sacred Flame.
High Elves, humans (both of Stormwind and Kul Tiras), and even the dwarves/earthen have the most welcoming / familiar presence thus far.
I could expect the presence of the Lightbound being equally accepted for their Holy presence and aura, but that’s just my opinion.
