I believe we shall find out eventually. They'd better have something good in store to make up for the "Morally Grey"-crap.
How are Loa so difficult to grasp..?
They are not good guys. They aren’t bad, but they are certainly not good. They want worship, they want souls and they like to fuck with people. They get a giant war where Darkspears and, soon, other trolls are going to slaughter enormous amounts of humans and co. What’s hard to understand..?
He picked the wrong Windrunner
This is what happens when you allow a half dead, pot smoking, juju worshiping troll to elect the future leadership of the Horde. Face it reds, you got trolled hard by da Darkspear!
I think the Loa were trying to save Zandalar when they told Vol'jin that Sylvanas was the chosen one.
They knew that she would bring the Horde to Zandalar, and that would help stop the Blood Trolls.
I've already, extensively argued over this stuff and I'm pretty sure there's nothing "fishy" about Vol'jin nominating Sylvanas, no matter what the current lore shows us: he had a vision from Loa, like it already happened to him and his father several other times, and took a decision based on that insight. How all these things together led to the nomination of no other but Sylvanas Windrunner? We clearly don't know yet and I'm not buying any Old God shenanigan. So it's either we have clearly yet to see how certain events unfold or what kind of development Sylvanas' character still awaits, despite the rather disheartening present.

Bwonsamdi can take all kind of souls under his care. Still, ignorant posters act like it was Bwonsamdi for certain who "suggested" anything when this is a baseless theory at best and headcanon at worst, plus Bwonsamdi needs rituals and a special connection to get the souls from the people who killed those bodies.
Ever did the Gorgrond quests with that laughing skull orc who gets told by the spirits to speak with a magnaron? It's probably the same reason.
I don't think Loas are necessarily benevolent beings.
