And we don’t have the slightest idea what he’s building it for.
For all we know, he was building it up in preparation for another Lich King style invasion of Azeroth and Sylvanas interrupted him.
The people in Org and SW spit and throw fruit. They don’t care why the DK were raised or if they were brave to break away. I’ll find it very odd and boring if everyone is just ok with the new ones.
I don’t think they will be ‘ok’ with it per-say. I mean one thing that we have to remember, is that the /spit and Fruit casting is a part of a very, very old line of coding from when DKs were first added in Wrath.
11 years have gone by, and I expect that while people dislike DKs still in some circles, they are probably much more accepted now, than they were in their original inception. Arthas had just attacked Orgrimmar, and the Scourge had raised hell across Kalimdor so it’s logical people would be touchy about it.
Somebody missed Legion.
DK story was one of the only good ones.
Might not be the same Lich King, but remember why Sylvanas is the way she is? Lich King started the raising business 
Ill reserve my judgement until i see how they implement it.
The lore has been so mangled I couldn’t care less any more.
Blizzard writing at its best.
